Changing Lanes

Before changing lanes, check your side and rearview mirrors for traffic approaching you from behind. Then, use your turn signal to let other drivers know you plan to change lanes. Check for other drivers who also may be moving into the same lane. Just before you begin moving into the other lane, quickly glance over your shoulder and check for any vehicles that may be in your blind spot.

Whether you are changing lanes, passing, entering or exiting a highway, always use your turn signals and check traffic to the rear and sides. When driving on a multi-lane highway, stay in the right lane if you are driving slower than the traffic around you.


When passing another vehicle:

Check the traffic ahead of you, behind you and in your blind spot before you attempt to pass. Signal and then accelerate to pass. Return to the right lane as soon as you can see the front of the passed vehicle in your rearview mirror.

It is against the law to exceed the speed limit as you pass.

Complete the pass before you reach a No Passing zone. If you’re still in the left lane when you reach the zone, you’re breaking the law.

You may pass on the right if the vehicle you are passing has signaled and is making a left turn. Be cautious because the vehicle you are passing may be blocking your view or blocking the view of other drivers. You may not pass on the right if you must drive off the pavement or main portion of the roadway to get around the other vehicle.

When approaching or passing a person riding a bicycle, moped, or power-assisted bicycle or other device, reduce speed and pass at least three feet to the left.

When being passed, don’t speed up. Maintain a steady speed or slow down.

Passing is unlawful and unsafe:

  • On hills, curves, at intersections or railroad crossings, except on roads with two or more lanes of traffic moving in the same direction
  • Off the pavement or shoulder of the road
  • When a school bus is stopped to load or unload passengers on a public road (unless a physical barrier or unpaved median separates traffic going in either direction) or on a private road
  • When a solid line marks the left side of your lane

Over-correcting occurs when the driver turns the steering wheel more sharply than expected, causing the rear wheels of the vehicle to slide toward the outside of the turn. This may result in the loss of vehicle control. Most over-correction crashes are single vehicle crashes and are often preventable. A driver should remain alert at all times. Reduce speed and use extra caution while driving on curved roads. If you veer off the road, curved or straight, do not panic. Gradually reduce your speed, look in the direction you want to go, slowly steer back onto the roadway.
