3. How does the Delaware manual tell you to judge your following distance?
Correct answer: Count at least three seconds between the vehicle ahead passing a fixed point and your arrival at it
Watch the rear of the car ahead go by a pole or sign, then count. Reaching the same spot before you finish the count means you are too close and should drop back.

4. What is the four-second sight distance rule for?
Correct answer: Checking whether you could stop within the distance you can actually see
Pick the farthest object you can see clearly and count to four. Getting there before you finish means you are outrunning your sight distance, and at night your headlights.

5. Which Delaware roads does the manual list at a 65 mph limit?
Correct answer: Route 1 and Interstate 495
Those two roads are singled out for sixty-five. Other controlled access highways stay at fifty-five, and under emergency conditions the posted figures may be changed.

6. In a heavy rain, at roughly what speed can tires lose their grip entirely and ride up on the water?
Correct answer: About 50 mph
Most tires hold well up to around thirty-five miles per hour on wet pavement, but in a downpour traction can vanish near fifty, and worn tires give up far sooner.

7. What does Delaware's general speed restriction mean for a driver in pouring rain?
Correct answer: Traveling at the posted limit can still be unlawful if it is unreasonable for the conditions
Nobody may drive faster than is reasonable given the conditions, so a driver can be ticketed for excessive speed even while staying below the sign.

8. How big a gap does the Delaware manual say you need in order to merge into traffic?
Correct answer: About four seconds
Entering at the midpoint of such an opening leaves you, and the driver who ends up behind you, each with a three second cushion.

9. Which situation calls for stretching your following distance to about four seconds?
Correct answer: Following a motorcycle
Slippery surfaces, motorcycles, heavy loads, poor visibility, drivers who cannot see you and being tailgated are all listed as reasons to add a fourth second.

10. By roughly how much does the Delaware manual suggest cutting your speed on a wet road?
Correct answer: By about 10 mph
Wet pavement calls for roughly ten miles per hour less. Packed snow calls for halving your speed, and ice calls for slowing to a crawl if you drive at all.

11. Unless a sign says otherwise, what is the speed limit in a Delaware residential district?
Correct answer: 25 mph
Residential and business districts share the same figure of twenty-five miles per hour in the manual's table of limits.

12. What does Delaware law say about driving unusually slowly?
Correct answer: You may not go so slowly that you obstruct the normal movement of traffic, unless safety demands it
Impeding the reasonable flow of traffic is prohibited, and posted minimum limits must be obeyed except where weather or other conditions make that unsafe.
