I always heard “2 seconds of space” which is a lot more than a few car lengths, to give yourself time to react to both what’s in front of you and to the sides, and account for if their brakes perform better than yours. Two seconds of distance is a lot, though, and kind of impractical in traffic.
The recommendation changed from car lengths to seconds decades ago, but wasn’t well communicated fwict. I learned car lengths from my dad and then seconds when I got my motorcycle endorsement.
If everyone were leaving 2 seconds of space, it also reduces stop and go traffic that is caused, or at least exacerbated, by the traffic wave phenomenon. But that’s even less well socialized.
In Ontario, that space you just left will immediately get filled by tailgaters, meaning you have to slow down more, which lets in more tailgaters. You have to drive aggressively as fuck to get to where you want to go in Ontario because everyone else driving on the road barely has a drivers license and is also driving aggressive as fuck (we passed basically everyone who applied for a driving test during the pandemic and eliminated all manoevers and skill checks).
Should be at least 5 car lengths on the highway
Lord I hate those fucking cunts who see two car lengths of space as an invitation. I’m going 85, you’re going 75, don’t suddenly hop in front of me because the clown in front of you is going 70.
You can’t do this in LA, but LA fucking sucks so fuck 'em haha.
Intelligent people leave a space of about two cars ahead of them on the freeway.
Stupid people think that space must be for them.
Two car lengths isn’t even remotely enough space if you’re traveling at high speeds.
Yeah, I follow the 3 second rule and try to keep 3 seconds of travel distance between me and the car in front of me
This is it. Absolute minimum two seconds in perfect conditions, four if it’s raining/dark/whatever.
It depends.
On a well developed well maintained “freeway” with multiple lanes, shoulders for break downs, gentle curves, et cetera it’s common. 3 car lengths is more common here I think.
That said, on a “highway” (interstate?) without everything listed above I aim for 2 seconds, which is about 60 metres at highway speed.
Intelligent people leave a whole fucking lot more than just two car lengths.
Back when i drove. I was taught 3 car lengths, or 3 seconds. Whichever is greater.
I think they’re saying 2 car lengths when in heavy traffic going 20 mph. I hope…
When i was 13 bill Clinton told me 1 car length per every 10mph i was traveling at. Ive been following that advice ever since
And I know it’s state dependent, but the highways by me, each white line is about one car and each gap is one car, so if you’re doing 50, having two to three white dashed lines between you and the car in front of you is probably good.
Fun fact: In most states, this length is 40ft, but there are some exceptions, like CA, where it’s 24ft or 48ft depending on the road.
What better place to keep em guessing than while behind the wheel on the highway!
3 seconds is the minimum safe distance, regardless of speed
What is this in imperial? How many bullets per square-child?
Depends, African or European?
3 seconds from you to get to where the other car was previously.
Yes
This is just plain untrue.
In all cases you need to drive to the conditions. Observe your circumstances and adapt your behavior accordingly.
3s is a good yard stick, but there’s plenty of situations in which it is not the ideal safe distance.
At 110km/h that’s about 90 metres. Every idiot around is going to try to move around you to take up that spot. Being overtaken by idiots is unsafe. This is just one example, there’s plenty of others.
If you see people weaving like crazy you just slow down even more.
I leave enough room for me to have time to react and give the person behind me enough time to react to my breaking. Because most people drive way too close to avoid a rear-end collision if I have to slam my breaks for an emergency. Sometimes that means I’m 4, 5 or 6 car lengths away from the car in front of me, but that has the added benefit of pissing off tailgators who will almost immediately choose to pass me which works out great for me. The less space the person behind gives, the more space I leave between me and the person in front.
Spoken like a true left lane hogger
Edit: OP is bragging about forcing cars behind them to pass on the right because they are too entitled to get the hell over. It’s dangerous and you people applaud them. Pathetic.
They never said they’re in the left lane, and in fact specifically specified against it. Sounds like you’re both defensive and an aggressive driver.
The vast majority of roads that allow legal passing are 2 lanes. Safe assumption to make. They didn’t clarify otherwise until a later comment. This thread is also days old and a settled conversation you are now interjecting into… why?
It’s Lemmy, and it took maybe 5 minutes of scrolling for this to be on my front page. Your comment irked me and I want to increase engagement on the site, sue me.
Spoken like a true entitled bad driver
If they’re matching the pace of the car ahead, explain the offense.
Left lane is for passing. The vehicle ahead of them could very well be just as in the wrong if not worse.
If you’re pacing the car in front of you, you’re already wrong.
Never. Pace. Strangers.
You pass them or let them pass.
Nope, I stay in the slow lane, unless my exit is in the left lane of course.
I just moved to Michigan
I have never seen a group of drivers so committed to Tail Gateing … Like it’s the state sport
Brake check!
Visit Tennessee and get back to me. Moving from Tennessee to Michigan I noticed a distinct uptick in the quality of driving.
cries in Houston TX
I swear Texas license plates are like warning signs for bad drivers
Wait till u get to DC, MD, and VA. that’ll make u cry even more.
I was driving in slowish freeway traffic in Detroit and the guy behind me plowed right into me, didn’t even slow down, didn’t even look away. He sort of bounced off of me, pulled onto the shoulder, and squeeled off while I had to find some sketchy spot to stop and make sure my bumper wasn’t dragging too much.
A person I was visiting there in Detroit told me that insurance wasn’t required so many people run off rather than risk getting blamed and the cops wouldn’t even bother with a report.
Insurance is required in all of Michigan, with fines, license suspension, and jail all possible for not having it. With Michigan’s no-fault insurance we have some of the highest rates in the country in Detroit—especially relative to income—and almost no viable alternative to owning a car.
That said, as a native Detroiter I feel safer in Detroit driving around other Detroiters, the suburbanites and out of state folks are always in the way.
I thought I heard that insurance laws changed maybe since then or around that time and there was a reason for a lot of hit and runs. I don’t know, but that was my experience a while ago. The weird part was mostly how the dude had no visible reaction at all except to take off, which probably could’ve been anywhere.
As an out of towner I did have trouble with the short on ramps. I wasn’t sure how to get into a rhythm because there was no place to get up to speed. I didn’t like feeling like I had to shove my way in and it was hard to tell how to let others in safely. I suppose you just know those things when you live there long enough.
Those are some of the first below-grade expressways built in the country, so the shorter on ramps are from an era with fewer and slower cars, and there isn’t space to lengthen them. The law only changed to stop the insurance companies from using zip codes to determine rates, and reduced the maximum payout for healthcare related costs from a crash, with the aim of lowering costs, but of course the insurance companies worked around it.
I learned about the infrastructure at the time but that’s why being unaccustomed was a hinderance, especially when it’s unexpected. The insurance stuff seems likely more in line with what I was told than what I was remembering in short.
yeah me too. i get a lot of rollerskaters squeezing into the space so i keep backing off til theyre all jammed ass to mouth like a human centipede. gotta keep my distance for when the chain binds. and it will
Robert Loggia and David Lynch have something to say about this:
I think my biggest pet peeve about driving is when you come to a stop and the car behind you tries to shove their nose up your ass. Like bruh you don’t need to ever be that close
Maybe they just really love the smell of exhaust and are trying to get high off of your emissions
Then get out and suck my tailpipe but stay off my ass lmao
At a stop? Who cares? Can’t being closer together at a stop light at least help with intersections? I guess it depends on the city.
If you’re driving a manual and you roll back on a stop, you shouldn’t be driving a manual. Unless you live in like San Francisco I guess? In the Appalachian region, cops will stop you for rolling back.
Ever heard of clear distance? If you’re at a stop and someone rear ends you and you hit the car in front of you you are at fault and will be held liable.
As for the rollback in my state they’ll again look at distance. Because if I don’t have enough space to back up because you’re too close you’re once again at fault for not having clear distance.
On top of all that it helps move traffic along faster. You don’t have to wait as long to accelerate if you maintain distance because you don’t have to wait for the car in front of you to move far enough to start accelerating.
Getting bumper to bumper has zero benefits outside of the false psychological feeling of forward progress.
Especially annoying if you’re driving a manual and are stopped on an incline.
I drive a 6 speed. This is where my rage for this comes from.
But even in automatics rollback isn’t uncommon on an incline.
I feel like it really isn’t your fault if you role back 6 inches and hit them. If you were to roll back 4 feet it would be different but in this case you can’t control something so small.
In court it won’t be your fault if they’re that close, but it’s still the hassle of dealing with people who don’t understand basic driving etiquette.
I can usually set off on an incline with no rollback but I’ll be damn if it doesn’t slightly stress me out every time someone pulls that shit.
My driving instructor taught me that I should still be able to see the other car’s back wheels when I stop. I actually don’t know how close that looks from the other driver’s perspective.
Terrible, terrible advice. That leaves a full car-length of empty pavement with the driver sight-lines of modern SUV and crossover designs. Pickup trucks are worse; I’ve seen pickup truck drivers stop a full 30 feet back. It wastes huge amounts of space on the street, and causes traffic congestion. On the other side of the coin, van and bus drivers can still get right up on your ass when following this advice.
I hate breathing in pollution so I keep a car’s length between me and the next car at traffic lights. Cars themselves are a huge storming waste of space and I hate being in or around cars with all my heart and soul so if I make traffic worse then I will consider it a passive form of protesting against car dependency
Respect!
What it looks like:
Not actually as the “see the tires” rule is fairly good advise. Keep in mind sometimes it is smarter to give a little more space depending on the situation. Think of it as more of a minimum. Also lose most of your speed farther back and then role forward. This allows for recovery time in case of failure or loss of traction.
if they are following the two second rule they should be less than a foot from your car. If your car is stopped you are always more than two seconds from the car in front of you.
I can’t believe this comedy gold is not upvoted more. Maybe it needs /s?
Never heard of that rule. I was always taught to leave enough space that you can see the bottom of their back tires.
The two second rule is for following distance. Applying it to stopped cars makes no sense at all, but it is funny . You have it right.
Ah I misunderstood. I understand it now.
I leave enough space to be able to drive around them if I need to
Id get that close if I want to give the phone enjoyer behind me plenty of time to stop
So you can hit the car in front of you too?
It’s not only a safety hazard but it leads to slower traffic. If you maintain the right distance at a stop the whole line of cars can accelerate faster because you don’t have to wait as long for the car ahead of you to move. There are zero actual benefits of sniffing my ass at a stop.
phone enjoyer is ungovernable
Weird guy is right though. Best practice is to leave enough space so that in the event you get rear ended you don’t get shoved into the car in front of you.
fair point
That doesn’t mean you should be acting like an asshat yourself.
It takes two to tango
calm down
The gap you leave should be speed-dependent and about 2 seconds to allow for reaction time. Yes, this caps the highway’s capacity to 0.5 cars per second per lane but roads are inherently inefficient.
I was taught to look when the car in front drives past a landmark like a lamppost, then say to myself “Only a fool breaks the two second rule”
If you pass the lamppost before you finish saying it, you’re too close
This is the only good answer. No need to distract yourself by figuring out your speed and guesstimating your gap like others are saying. Just count the seconds whenever you need to
Aye, and 2 seconds is the bare minimum. A company I have worked for wanted 4 seconds between you and the car in front. That always felt a little much, but it definitely helped prevent wrecks.
2 seconds assumes an instantaneous reaction and perfect road conditions. In the EU they’ll teach you about 3s and at least +1 in poor conditions.
In my state, it’s one car length(15-20 feet) for every 10mph. Good luck getting anyone to actually follow it though! Getting on a major highway here is like the Autobahn.
3 seconds is the guideline I’ve been taught here in Sweden, but yeah. Riding too close is crazy dangerous and I don’t understand why people keep doing it.
2 isn’t much, over here they recommend 3 at highway speeds
If you’re only two lengths away from the car in front of you while driving at highway speeds, you are tailgating. Back off. It’s far more dangerous than speeding.
Help me out with this, because it’s driving me crazy. Whenever I leave anywhere close to 2 seconds between me and the car on front of me, someone cuts in, and I’m now too close to them, so I slow down, leaving a 2 second gap, and another cuts in. Rinse, repeat. I end up being the slow ass that everyone keeps zooming around unless I tailgate.
Just… Don’t care? Let people in and adjust the distance with them. Driving is an involved process, get a car with adaptive cruise control if you want one that will do exactly that for you.
I guess it’s more than just “caring” - I feel that we’d all be a lot safer if we were all going the same speed instead of inviting people to dodge in and out
It would be safer if we were all riding the train/bus. Getting in a car in america is accepting the risk that you share the road with everyone. no matter the qualifications or mental state we still all gotta get to work/grocery store/wherever, and the only way is by ~4000 pound metal speed box.
Worrying about safety on the highway is about making sure you are in situations you can handle and react to, staying attentive to the styles and mental states of other drivers and being a step ahead of the road conditions
Unfortunately I can’t see how public transport would be feasible without accepting that the vast majority of places I might want to go are simply inaccessible, and the places I could go would take 3-5 times longer. Case in point, there are no public transportation options to get to my son’s high school. It would be a 35 minute bicycle ride. I can drive there in 12 minutes. Getting to my local Wegmans would take 37 minutes by bus. I can drive there in 9 minutes. I live on the outskirts of a medium size city on the east coast in a low density residential neighborhood.
But people need to change lane sometimes and if you’re the one giving them the space to do so then more power to you, don’t complain
It just be that way. Idiots will see your safe following distance as their opportunity to switch lanes. Just keep being the safe one.

Beyond “don’t care” - you get to be the traffic hacker who improves traffic for everyone. yayyy
Credit for above I think: Traffic Waves
Anyone who wants to test how this can work?
Check this old-school site:
Let them hop in and keep your 2 seconds. I used to have a 40 minute commute and on a busy morning would have 10-15 people do that. Know how much time that sets me back? 20 to 30 seconds. Following this rule I have a 25 year clean driving record and I guarantee these lane hoppers can’t make that claim
it’s probably even less, maybe even negligible because of traffic lights at either end: you can’t calculate a single journey because you’re never going to hit the same light exactly the same every time. I have four lights between my house and the freeway, and 7 between the freeway and one of the sites for my job. Each one adds between 0-60 seconds randomly for an average of 6 minutes sitting and waiting per day. I would have to have a commute of like 120 miles of uninterrupted freeway driving for that to matter.
Just be safe. You’re still close to your desires speed
At 65mph, you cover two car lengths (~30 ft) in about 1/3 of a second.
Typically human reaction time for braking is about 1.5 seconds.
If something went seriously wrong in front of you (like a sideways car, or a hidden obstacle in front of the car in front of you) you would have covered 10 car lengths before your foot touches the brake pedal.
