When it is difficult to see due to darkness or poor weather, increase your following distance. This will give you more time to react to hazards that you may not see in advance.

Downward-facing triangular signs usually indicate that drivers should yield. Once the road is clear of traffic or pedestrians and it is safe to do so, drivers may proceed.

A flashing red traffic light means the same thing as a stop sign. When arriving at an intersection with a flashing red light, you must come to a full stop and proceed when it is safe to do so.

A bicycle is difficult to see in the dark, even when the cyclist is wearing a proper headlight and reflector. Both motorists and bicyclists should be especially alert when driving at night in order to prevent dangerous collisions.

Defensive driving is using safe driving strategies to prevent crashes. This means that you alter your driving to fit the weather conditions, the way you feel, and the actions of other drivers, bicyclists, and pedestrians.

Warning signs prepare drivers for upcoming road conditions and hazards and are usually yellow with black markings. This sign tells drivers that there is an upcoming stop sign and that they should prepare to come to a complete stop before proceeding.

Arrows may be used to indicate which lanes should be used for specific purposes, such as driving straight or making a turn.

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.

In a school zone, the speed limit is 25 miles per hour. If a different speed limit is posted, follow the posted speed limit.

When facing a green light, you must yield to pedestrians and vehicles already in the intersection. Drivers must yield to pedestrians when turning on a steady green signal.

This sign indicates that the road may be slippery when wet. Exercise caution when driving on a slippery road.

Orange, diamond-shaped signs are used to mark construction, maintenance, survey, and utility work areas. These signs help direct drivers and pedestrians safely through dangerous zones. Fines for traffic convictions may double in areas marked by these signs.

Bring your vehicle to a complete stop at a crosswalk to yield the right-of-way to any vehicle or pedestrian already in the intersection. You may carefully proceed if your lane is completely clear.

If you notice that the road ahead is covered by heavy smoke, reduce your speed immediately, drive as far as possible to the right, and stop off the roadway. Only then should you determine if it is safe for you to continue. Remember that certain kinds of smoke can irritate your eyes and lungs or even kill you.

Passing areas are based on how far ahead drivers can see. Allow the passing vehicle to re-enter the drive lane as easily as possible to help everyone avoid potential upcoming hazards.

Rubbernecking (the practice of slowing down to look at collisions or other out-of-the-ordinary things) contributes to traffic congestion and should be avoided.

This sign marks parking spaces that are reserved for people with disabled parking permits.

Blind or partially blind pedestrians may carry a white cane or use the assistance of a guide dog. You must always yield the right-of-way to a pedestrian who is using a guide dog or carrying a white cane.

If you pass on the right, do so only when conditions permit you to pass legally and safely. Under no circumstances are you allowed to drive off the pavement or onto the shoulder to pass another vehicle.

Locations where it is unlawful and unsafe to pass another vehicle include hills, curves, intersections, and railroad crossings.
