some states it is against the law to drive in the left lane UNLESS you are passing. This is do to emergency vehicles using the left lane and being blocked by people not paying attention. You can get a ticket for driving in the left lane in some states. No , most cops dont give them, BUT if you impeed the passing of an ambulance do to it, and there is a cop around, look out.
When you drive slow!! And if you do, you really need to be in the right lane. Because if you drive slow in the left lane, you'll really (really) make people mad!
The left most lane
If there are 3 lanes on your side of the freeway, the right-hand lane is there for vehicles to merge onto the freeway and it is the place for slower moving vehicles to drive; such as big rigs or cars towing anything. The lane in the middle is the passing lane for slow moving traffic, and it is the lane for primary travel of other than slow moving vehicles. The lane to the far left is for passing only, except when designated for specific use, like a carpool lane.
The fast lane is typically the leftmost lane on a multi-lane highway or freeway.
shoulder
1 lane is the lane "fast lane" all the way to left, it counts up after that ---- When facing the direction of traffic flow, traffic lanes are numbered from left to right. The lane closest to the center median is the number 1 lane. The "slow" lane (closest to freeway entrance/exits) is numbered according to the total number of lanes. (anywhere from 2 to 6)
Merge into the nearest left lane when it is safe to do so.
Drivers intending to stay on the highway/freeway should stay in the right lane or the lane designated as a through-lane. The only times you should move left is to allow vehicles to merge from a right side on ramp (and move back to the right lane as soon as you can), or to pass slower traffic already in the right lane (then move back to the right lane when it is safe to do so). If a freeway provides a "slower" lane and you drive slower than the maximum speed allowed, you should use the slower lane. But never hog the passing lane just to keep driving in it; move over and let faster traffic pass you.
you should safely change to the right lane
On a four lane road you may drive in the left lane if you are passing a car in the right lane or, if you are moving at the prevailing speed of other traffic in that lane.
Yes, you must drive in the right lane if there are no vehicles in the right lane according to RSMo 304.015 charge code 4722705.0. The left lane is for passing only.
The right lane is the lane to always drive in. The left lane is to be used for a passing lane.
If the left lane is ending, and merging into the right lane, then the car already in the right lane has right of way.
