How far ahead does the Delaware manual recommend scanning to avoid last-second decisions?
Correct answer: At least the distance you will travel in 10 seconds.
The manual recommends looking at least 10 seconds ahead. Keep checking the sides and rear as well; looking ahead does not mean staring at one fixed point.

In ordinary good conditions, what method does the manual give for checking your basic following distance behind a car?
Correct answer: Stay at least three seconds behind it using a fixed roadside reference.
The three-second method adjusts the distance with speed. Pick a fixed point the leading car passes, then count until you reach it.

Rain makes the road slippery. How should your following space change?
Correct answer: Increase it beyond the ordinary good-condition gap.
Slippery roads increase stopping needs. More following space gives you time and room if the vehicle ahead brakes suddenly.

A driver is following very closely, and a right lane is available. What is the safer response?
Correct answer: Move right when safe and let the driver pass.
The manual advises moving right when possible. Sudden braking increases the chance of being struck from behind.

A sharp curve is ahead. When is the best time to reduce to an appropriate speed?
Correct answer: Before entering the curve.
Slowing before the curve preserves traction and reduces the need for braking while turning. Entering too fast can exceed the tires' grip.

The posted speed is 50 mph, but heavy rain makes that speed unsafe. What does Delaware require?
Correct answer: Reduce speed to what is reasonable for the conditions.
Both posted limits and the general reasonable-speed requirement apply. A posted maximum does not guarantee safety in rain, poor visibility or heavy traffic.

Unless another posted limit governs, which maximum does the manual list for a residential district?
Correct answer: 25 mph.

Conditions are good, but a driver travels so slowly that normal traffic is obstructed without a safety or legal reason. Is that acceptable?
Correct answer: No; unnecessarily impeding normal reasonable traffic is prohibited.
The manual prohibits obstructing normal reasonable traffic by unnecessarily slow driving. Necessary safety reductions and compliance with law remain valid reasons to slow.

You are in a school zone with children present, and no different posted or emergency rule applies. Which limit does the manual list?
Correct answer: 20 mph.
The manual lists 20 mph for school zones when children are present. Stay alert for children and reduce speed further whenever needed for safety.

Outside a district or zone with a lower limit, what maximum does the manual list for an ordinary two-lane road when no different posted limit applies?
Correct answer: 50 mph.
The table lists 50 mph for two-lane roads. A different posted limit and the requirement to slow for unsafe conditions still control.
