This sign warns that there is a steep hill ahead.

When driving near heavy trucks, other drivers and highway users must make allowances for the increased stopping distance required by the large vehicles. Drivers of smaller vehicles should remain in locations where they can be seen by the driver of the large vehicle and where their view of traffic is not blocked by the vehicle.

If you follow too closely and the vehicle in front of you slows or stops suddenly, you may not have enough time to avoid a collision.

When a school bus is stopped on the road ahead with its lights flashing and its stop arm extended, you must come to a complete stop and wait to proceed until the lights have stopped flashing and the stop arm is withdrawn. Even after the bus begins to move again, do not proceed until you are sure there are no children crossing the road ahead of you.

You should never change lanes within an intersection. Before changing lanes, always look over your shoulder to check your blind spot. Be alert to other drivers moving into the same lane.

A "No stopping" sign means you can only stop to obey a traffic signal, to obey a police officer, or to prevent a conflict with another vehicle.

When you park on a downward-facing slope, turn your wheels sharply toward the side of the road. This way, if your vehicle starts to roll downhill, it will roll away from traffic.

If you stop along the road at night, turn on your emergency flashers and leave your low beam headlights turned on. Be sure that other road users will be able to clearly see your vehicle.

This sign indicates that U-turns are prohibited.

Alcohol negatively affects many skills needed for safe driving, including your reaction time and ability to see clearly. It can also harm your judgment of speed and distance, lower your inhibitions, and make you more prone to taking chances.

Drinking coffee will not reduce your blood alcohol concentration (BAC). While it may help you to stay awake, it cannot change your BAC or make you sober.

A downward-facing triangular sign is always a yield sign. Drivers must be prepared to slow down or stop when approaching a yield sign.

The slow-moving vehicle symbol is a reflective orange triangle. Expect vehicles using this emblem to be driving at speeds of 25 mph or slower.

At intersections that are controlled by signs or signals and at intersections that are uncontrolled, the driver on the left must yield the right-of-way to the driver on the right when two vehicles arrive to the intersection at the same time.

If conditions are safe and legal for passing, check in your mirrors and signal your lane change. Before you pull into the left lane, look quickly over your left shoulder to make sure there is no vehicle in your blind spot.

When braking on slippery surfaces, such as roads covered in snow or ice, you should apply your brakes steadily and slowly to avoid locking your brakes. Apply the brakes earlier than you would on a different surface to allow your vehicle extra time to safely slow down.
