You must come to a complete stop at a steady or flashing red traffic light. You must always obey instructions given by officers directing traffic, regardless of any posted signs or traffic signals.

Because your tires will not grip the road under wet, snowy, or icy conditions as well as they will under dry conditions, you should slow down if the roadway is wet or icy.

If you become tired while driving, it is best to stop to rest or change drivers. Being tired dulls your mind and slows down your reactions, making driving hazardous.

Hydroplaning is caused by driving too fast on a wet road. Slow down when driving on wet pavement to prevent hydroplaning.

Motorcyclists have the right to use a complete traffic lane, but two motorcyclists may share a lane if they choose to do so. Do not pass a motorcycle within the same lane.

This sign marks the presence of a crosswalk. Be alert to any pedestrians that may be crossing the roadway.

When driving in heavy rain at speeds as low as 30 mph, your tires may lose all contact with the road and instead ride up on a layer of water above the surface of the road. This is called "hydroplaning." If your vehicle starts to hydroplane, slow down gradually and do not apply the brakes.

You must drive more slowly than usual when there is heavy traffic or bad weather. However, if you block the normal and reasonable movement of traffic by driving too slowly, you may be cited. You should match the speed of traffic, unless the speed of traffic exceeds the legal speed limit.

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.

You may encounter unexpected conditions in a construction zone. For the safety of yourself, other drivers, and construction workers, drive with extraordinary caution.

Tailgating is a common behavior that can lead to aggressive driving, and so it should be avoided. Drivers may face legal consequences for driving unsafely.

If you are being followed too closely by another driver, merge into a different lane. If there is no lane available for merging, wait until the road ahead is clear and slowly reduce your speed. This will encourage the tailgater to drive around you.

Signs with a red circle and diagonal line over a black symbol indicate that the action represented by the symbol is prohibited. In this case, the sign indicates that left turns are prohibited.

Drivers making a left turn must yield to all vehicles approaching from the opposite direction. This includes bicycles and motorcycles.

When traffic control signals are not working, a driver must always treat the intersection as an all-way stop and come to a complete stop, unless otherwise directed by law enforcement. The driver must then look and yield the right-of-way before entering the intersection.

Never pass within intersections or at other intersecting points, such as parking lot entrances and alleyways. Any time your view is blocked by a curve or a hill, you should stay in your lane and assume that there is an oncoming vehicle just out of sight. Wherever signs and/or pavement markings permit passing other vehicles, you will have to determine whether or not you have enough space to pass in a safe manner.

Before changing lanes, you should check your side mirrors and look over your shoulder to make sure it is safe to proceed.

White lines between lanes indicate that the lanes are traveling in the same direction. Broken white line markings indicate that it is legal to pass another vehicle when safe.

When entering any roadway, you must be aware of traffic conditions. Use your side mirror and look over your shoulder to help you see and anticipate traffic when entering a freeway.

Yellow lines separate traffic moving in opposite directions. Dashed lines on the pavement indicate that passing is permitted when safe.

When passing is permitted, look for both headlights of the passed vehicle in your rearview mirror. Only then may you safely return to your original lane.

Warning signs are usually yellow with black markings. They alert you to conditions that are immediately ahead. This sign warns drivers about an upcoming winding road.

A green arrow means "go." You must turn in the direction the arrow is pointing after you yield to any vehicles, bicycles, or pedestrians who are still in the intersection.

The flashing overhead lights and stop arm on a school bus will be activated when the bus is stopped to load or unload students. If approaching a bus using these signals, you may not proceed until the red lights have stopped flashing and the stop arm has been retracted. Never pass a school bus that is dropping off or picking up students.

When making any turn, turn from the lane closest to the direction you wish to travel into the first available legal lane. On a turn from a two-way to a one-way street, this means you should turn into the first lane.
