If a tire blows out or suddenly goes flat while you are driving, grip the steering wheel firmly and keep the vehicle aiming straight. Take your foot off the accelerator and do not brake. Allow the vehicle to slow by itself and use the brakes gently, but only if necessary. Pull off the road when it is safe to do so.

This sign is posted on one-way streets and other roadways where a driver is not allowed to enter. A driver may see this sign if attempting to enter an expressway ramp in the wrong direction.

Orange-colored signs indicate construction areas. Proceed with caution.

As daylight begins to fade, turn on your low beams to help others see you. Only use your high beam headlights in an open area where no other drivers are present.

Yellow lane markings indicate a separation of lanes where traffic is traveling in opposite directions. When you see double solid yellow lane markings, passing is prohibited from both directions.

When traffic permits, you should make room to allow vehicles to merge into your lane.

In rainy weather, you should lower your speed to reduce the risk of hydroplaning. Driving too fast may cause your tires to ride up on the water and lose contact with the surface of the road, making it very difficult to control your vehicle.

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.
