"Reduced speed" signs inform drivers that they must reduce their speeds. If a new speed limit is posted on one of these signs, the new speed limit begins at the sign.

If you are being tailgated by another driver and there is a right lane, move over to the right. If there is no right lane, wait until the road ahead is clear and then reduce your speed slowly. This will encourage the tailgater to drive around you. Never slow down abruptly as this will only increase the risk of your vehicle being hit from behind.

To prevent drowsiness on long trips, you should schedule regular stops. Give yourself time to rest and stretch, even if you are not feeling tired.

You must yield the right-of-way to police cars, fire engines, ambulances, or any other emergency vehicles using a siren or air horn and a red or blue flashing light. Follow any instructions given over the emergency vehicles' loudspeakers. Emergency vehicles often follow each other so you should proceed only when you are certain the way is clear.

When approaching a flashing red signal, you must stop and yield to all traffic that does not have to stop.

Yellow lines separate traffic moving in opposite directions. A single dashed yellow line in the center of a road indicates that vehicles traveling in both directions are permitted to pass. Drivers may only begin a pass if they will not interfere with any oncoming traffic.

Be very cautious any time you encounter an animal on the roadway. Pass the animal slowly to avoid startling or frightening it.
