Activate your turn signal before beginning a turn to alert surrounding drivers to your intentions. Complete the turn before turning off your signal.

You should turn your head to check your blind spots before every lane change.

Your horn should be used as a warning in situations where you think another driver or a pedestrian does not see you. For example, if a child begins to run into the street in front of your vehicle, you should sound your horn.

If another driver is threatening you or intentionally driving dangerously around you, remain calm and try to put as much distance between the two of you as possible. Slow down and let them pass. Do not make eye contact and do not make obscene gestures.

Instructions given by police officers directing traffic always override posted traffic signals and signs. Follow the officer's instructions.

Many kinds of drugs can impair your ability to drive. This includes illegal drugs and legal prescription or over-the-counter medications. It can be a criminal offense to drive while impaired by any drug.

To avoid being blinded when driving at night, do not look directly at the headlights of oncoming cars. Instead, look toward the right edge of the road until the oncoming driver has passed.

When approaching a roundabout, you should slow down. A roundabout is designed to be driven at a low speed.

You should be extra careful when turning and stopping during the first half hour of rain. At this point, the oil from cars has not yet washed off the pavement and could be forming a slippery mixture with the rain.

If you intend to make a turnabout, you must first be sure that it is permitted in the area. Observe your surroundings and check for hills and curves, signs prohibiting turnabouts, double yellow lines, traffic, and visibility.

As driving speeds increase, the chance of a fatality in the case of a collision increases. If you are going faster than 80 miles per hour, you have almost no chance of living through a crash. The speed you drive affects your stopping distance, so you should increase your following distance as you increase your speed.

Use low beam headlights when driving in fog, rain, or snow. High beams may reflect off of the weather and make visibility even poorer.

You must yield the right-of-way to any emergency vehicle that is using its siren or flashing lights.

A flashing yellow traffic light means drivers should slow down and proceed with caution.

Decrease your speed as you approach an intersection with a yield sign. Prepare to stop and yield the right-of-way to vehicles and pedestrians in the intersection or crossroad. You must come to a full stop at a yield sign if traffic conditions require it.

This sign (with the arrow below) indicates the location of a bicycle crossing/path. Drive with caution around this sign because bicycles likely regularly cross or ride beside traffic in the area.

Do not drive in someone else’s blind spot. Move forward or drop back so that the other driver can see you.

This sign indicates that workers may be on or very close to the roadway ahead, so you should take special care when traveling through the area.

To avoid contributing to chronic traffic congestion, you should not "rubberneck." That is, you should not slow down to look at out-of-the-ordinary things.

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

Always use the proper turn signal when changing lanes, pulling into or out of a parking space, or pulling into traffic from an alley or parking area. Communicate with other drivers on the road to help prevent accidents.

Warning signs are used to warn drivers about upcoming hazardous conditions and are usually yellow with black markings. This sign warns drivers that an upcoming bridge may be too narrow to meet or pass a truck and that they should be careful.

Bicycles on the road are considered vehicles and have the same rights and responsibilities as motor vehicles. Drivers of motor vehicles should respect the rights of bicyclists.

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.

When approaching railroad tracks, you should look, listen, slow down, and be prepared to stop for trains or other vehicles that may be using the rails.

Before you return to the driving lane when completing a pass, be sure there is a safe gap between your vehicle and the passed vehicle. When you can see both headlights of the vehicle in your rearview mirror, it is safe to return to the driving lane.

Never try to pass more than one vehicle at a time. Only pass another vehicle when it is safe and legal to do so.

Drivers of trucks, buses, vans, and any vehicles pulling campers or trailers may not be able to see you if you are driving directly behind them. Increase your following distance when driving behind one of these vehicles. Additionally, large vehicles can block your view of the road, so increase your following distance to look around the sides of the vehicle and see the road ahead.

In many collisions with motorcycles, bicycles, and pedestrians, drivers reported that they were looking but still did not see the smaller vehicle or pedestrian. These can be more difficult to spot in traffic than passenger vehicles because they are smaller, may move faster, and have less noticeable lighting. To prevent collisions with these smaller and less protected road users, drivers should always be alert to the presence of motorcycles, bikes, and pedestrians.

Drivers must yield the right-of-way to pedestrians who are crossing the street in any marked or unmarked crosswalk. In the interest of safety, drivers should yield the right-of-way to people crossing any street.
