At a yield sign, you must slow down or stop, if necessary, and give the right-of-way to crossing or merging vehicles. Yield the right-of-way to any cross traffic that is close enough to cause conflict.

This sign indicates that the right lane on a multilane roadway ends ahead. Traffic in the right lane must merge left.

If you are being tailgated by another driver and there is a right lane, move over to the right. If there is no right lane, wait until the road ahead is clear and then reduce your speed slowly.

This sign indicates that the road ahead curves to the right.

A green arrow displayed on a traffic signal tells drivers that they may turn in the direction of the arrow. You must be in the proper lane for such a turn. Yield the right-of-way to vehicles and pedestrians already in the intersection.

The presence of solid or broken lane markings down the center of a road is the best indication of whether or not passing is permitted in an area. On a two-lane highway, you may not pass another vehicle if your lane is directly next to a solid line. You may not pass within 100 feet of an intersection.

Before you return to your driving lane, be sure you are not dangerously close to the vehicle you have just passed. One way to do this is to look for the vehicle in your inside rearview mirror. When you can see both headlights in your rearview mirror, you may have enough room to return to your driving lane.

You should communicate with other motorists, bicyclists, and pedestrians by doing things like signaling when slowing down, stopping, or changing direction. Use your emergency signals or horn when appropriate.

Before you drive, always fasten your seat belt and make sure all your passengers are using seat belts or child restraints. Studies have shown that if you use seat belts, your chances of being hurt or killed in a traffic crash are greatly reduced. Children age 12 and under should always ride properly restrained in a rear seat. Never put a rear-facing infant restraint in the front seat of a vehicle with a front passenger airbag.

When parking uphill on a road that has a curb, your wheels should be turned away from the curb. When parking uphill on a street without a curb or when parking downhill, your wheels should be turned toward the curb or edge of the road.

Bicycles do not have turn signals so bicyclists use hand and arm signals to alert other drivers to their intentions. If a bicyclist puts their left arm straight out, they are signaling that they intend to turn left.

If your vehicle begins to skid, do not use the brakes. Braking could make the skid worse.
