You should always look behind you to check for traffic when backing up. Only back up where it is safe and legal to do so.

You must yield the right-of-way to police cars, fire engines, ambulances, or any other emergency vehicles using a siren or air horn and a red or blue flashing light. Follow any instructions given over the emergency vehicles' loudspeakers. Emergency vehicles often follow each other so you should proceed only when you are certain the way is clear.

When driving in high-speed traffic, it is extremely important to stay well behind the vehicle in front of you. As your speed increases, the distance it will take for your vehicle to stop also increases.

To prevent yourself from becoming an aggressive driver, concentrate on driving and don't take the actions of other drivers personally. Be realistic about your travel time, drive within posted speed limits, and be forgiving of other drivers using the roadway.

You may only make a left turn at a red light when turning from a one-way street onto another one-way street. You should complete a left turn into the legal lane nearest to your previous lane.

A motorcycle is a full-size vehicle with the same privileges as any other vehicle on the roadway. You should allow a motorcyclist a full lane width. Although it may seem as though there is enough room in the traffic lane for a larger vehicle and a motorcycle, remember that the motorcycle needs room to maneuver safely.

If you hit a parked vehicle or other property, you must leave a note with your name, phone number, and address securely attached to the vehicle or property that you hit.

Guide signs, sometimes known as destination signs, have a green background and provide directional and mileage information to specific destinations. They can be a helpful resource when driving in unfamiliar locations.

Drivers must always yield the right-of-way to pedestrians in the roadway, even if there is not a marked crosswalk.

Do not stop at an accident scene unless you are involved or emergency help has not yet arrived. Keep your attention on your driving and keep moving, watching for people who might be on or near the road. Never drive to the scene of an accident, fire, or other disaster just to look.

Driving more slowly than other traffic can be dangerous. Drivers behind you may become impatient and will be tempted to take dangerous risks to pass you.

When you see a sign indicating that your exit is approaching, begin preparing for it. Signal and move into the exit lane as soon as you reach it. Once you are in the deceleration lane, reduce your speed gradually and slow to the posted exit speed.

Maintain a firm grip on the steering wheel and be ready to apply your brakes to avoid being pushed into another vehicle.

The most common mistake that drivers make when backing up is failing to look both ways behind them. Mirrors do not give you a full view. To see as much as possible, turn your body and head to the right and look through the rear window.
