Traffic: HOW TO PASS ON THE LEFT

HOW TO PASS ON THE LEFT
The left lane is normally used to pass other vehicles. You can not pass a vehicle
on the left if:

Your lane has a solid yellow center line.

You can not safely return to the right lane before you reach a solid yellow center line for the right lane.

You can not safely return to the right lane before any oncoming vehicle comes within 200 feet (60 m) of you.

You approach a curve or the top of a hill on a two-way road and can not see around or over it.

You are within 100 feet (30 m) of a railroad crossing on a two-way roadway.

You are within 100 feet (30 m) of a bridge, tunnel or viaduct on a two-way road and your view is obstructed.

 If you try to pass, you will interfere with oncoming traffic.

     If conditions are correct to pass, check in your mirrors and signal your lane change. Before you pull into the left lane, look quickly over your left shoulder, through the back side window, to make sure there is no vehicle close behind you in the left lane. Never depend on your mirrors when you prepare to change lanes. Even correctly adjusted mirrors will leave “blind spots” behind both sides of your vehicle.
If a vehicle is in the blind spot, you may not see it in your mirrors. Always quickly
look over your shoulder before you change lanes or pass.
     When you pass, move completely into the left lane. Before you return to the
right lane, signal and look at your interior rear-view mirror and make sure you can
see the front bumper of the vehicle you passed. Look quickly over your right
shoulder to make sure that you can see at least several feet of pavement between
your vehicle and the one you passed. Then return to the right lane.
