This sign warns of an upcoming winding road with three or more curves.

Before passing, you must make sure the passing lane is clear and give the proper turn signal to show you are going to change lanes.

If you miss your exit, you should take the next exit. Do not stop or back up on the highway, swerve across multiple lanes to try to make the exit at the last second, or cross over the median to turn around. All of these maneuvers are illegal and extremely dangerous.

On dry pavement, you should generally allow a cushion of at least four seconds between you and the vehicle ahead.

You are required to stop at all railroad crossings when a signal warns of an approaching train. These signals may include flashing red lights, a lowered crossing gate, a flagger signaling, or a train’s audible signal of warning. Do not move forward or attempt to go around any gate or ignore any signal of an approaching train.

Even if you are not driving, your driving privilege will be suspended if you are under 21 years of age and are convicted of possessing alcohol, lying about your age to obtain alcohol, or carrying a false ID card. The minimum penalties include a fine of $500, plus court costs, and a 90-day license suspension for the first offense.

This triangular sign is a "Yield" sign. When you see this sign, you must slow down to check for traffic and yield the right-of-way to pedestrians and approaching cross traffic. Stop only if it is necessary to do so.

Smoking while driving can create dangerous distractions by causing you to take your hands off the wheel and/or your eyes off the road.

When parking on an incline where there is a curb, you should turn your wheels sharply to the left, away from the curb. This way, if your brakes fail, your vehicle will not roll into traffic.

If you are underage and are arrested and detained for blood, breath and/or urine testing, parental consent to conduct these tests is not required; however, the police will notify your parents of the arrest.

This sign indicates that the road ahead becomes a divided highway. Keep to the right of the divider or median.

On dry pavement, four seconds of space is generally a safe following distance to allow between you and the vehicle ahead. You should always allow plenty of space when following a motorcycle.

When the road is wet or slippery, when you cannot see well, or when anything else makes conditions less than perfect, drive below the posted speed limit. Even if you are driving within the posted speed limit, you can still be ticketed for driving too fast for conditions.

This sign warns that especially slippery conditions exist when the road is wet.

When there is more than one potential hazard on the road, you should ensure that you only have to deal with one of them at a time. For example, when there is a bicyclist on the right that you want to pass and an oncoming car to the left, you should not try to squeeze between both at the same time. Instead, let the oncoming car pass, and then pass the bicyclist.

This sign indicates where a lane is reserved for the exclusive use of left-turning vehicles from either direction. Such a lane may not be used for passing or for through-traffic.

Warning signs, which tell you about conditions on or near the road ahead, are usually diamond-shaped with black symbols or words on a yellow background.

If a yellow panel with the message "Exit only" is on a highway sign, the lane below the sign will not continue through the interchange. Instead, the lane will go off of the roadway to form a ramp. If you are in a lane directly under an "Exit only" sign, you may change lanes to move through the interchange or you must exit the highway.
