A 3-minute lesson from the Delaware course. Read the rules and examples, follow the handbook page references, and check your understanding before you move on.
Warning signs alert you to hazards or special situations ahead so you can slow down and be ready to stop. Most are yellow diamonds with black symbols, and a few special shapes carry specific meanings.
Know the rule
Warning signs are usually yellow with black lettering or symbols, and most are diamond-shaped.
School sign (five-sided) and railroad advance warning sign (round)
Know the rule
The five-sided black-on-yellow sign warns only of schools and school crossings: slow down, watch for children and stop as needed. New fluorescent yellow-green versions may also be used.
The round black-on-yellow sign is the advance warning for a highway–rail intersection. Slow down, watch for the crossing, and use particular caution at night to avoid driving into the side of a train.
Traffic is backing up where two lanes become one. Using the zipper merge, you stay in your lane up to the merge point, then alternate with the driver in the other lane instead of squeezing in early.
