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.

Treat a flashing red light the same as a stop sign. Come to a complete stop at the stop line or, if there is no stop line, prior to the crosswalk and before entering the intersection. Yield to all other traffic and pedestrians.

An octagonal sign always means stop. When approaching a stop sign, you must come to a complete stop at the marked stop line and proceed only when it is safe to do so. If there is no stop line, stop before the crosswalk. If there is no crosswalk, stop before the intersection at a point from which you can see oncoming traffic.

To do your part to prevent road rage, you should follow laws, signs, signals, and pavement markings. Always signal your intention when changing lanes.

To prevent hydroplaning, lower your speed in response to wet roads and keep your tires in good condition. If you detect a loss of control, take your foot off the gas, do not apply the brakes, maintain the direction of the vehicle, and allow the vehicle to slow to a manageable speed.

Allow for extra space when driving behind a motorcycle. Motorcycles can stop more quickly than other vehicles can and you must have adequate room to stop if the motorcyclist brakes or falls off. Also, remember that motorcycles are difficult to see at night because they only have one tail light.

Never assume other drivers will give you the right-of-way. Yield your right-of-way whenever it helps prevent collisions.

You must turn on your headlights any time conditions prevent you from seeing other vehicles. Other drivers may have trouble seeing you, too.

The only way to sober up after drinking alcohol is to allow time for your body to eliminate the alcohol in your system. Nothing you can do, including eating and drinking, can accelerate this process.
