1. Modern roundabouts are engineered so that vehicles inside the circle travel no faster than what speed?
Correct answer: 30 mph
Tight diameters and curved entries hold circulating traffic to 30 mph or less, which is much of the reason these intersections are safer than ordinary ones. Anyone entering must wait for a gap and give way to traffic already going around.
2. You are driving at the posted speed limit, but it is raining hard and traffic is heavy. What does New York's basic speed rule require?
Correct answer: You must reduce your speed to what is safe for the conditions
The posted limit is the maximum for ideal conditions. The basic speed rule requires you to drive at a speed that is reasonable and safe for the actual conditions, so slow down in rain, snow, fog, or heavy traffic.
3. What is hydroplaning?
Correct answer: Tires losing their grip because they ride up on a film of water
In heavy rain the tires can climb onto the water instead of gripping the surface, and both traction and steering vanish. Higher speeds bring it on, and shallow tread or low tire pressure makes it likelier. Ease off the accelerator and cut your speed further when rain is heavy.

4. The 'two-second rule' in the New York manual helps you judge:
Correct answer: A safe following distance behind the vehicle ahead
Pick a fixed object ahead; when the vehicle in front passes it, count 'one-thousand-one, one-thousand-two.' If you reach the object before you finish counting, you are following too closely.
5. You have just taken an exit ramp off an expressway. What should you do about your speed?
Correct answer: Read the posted limit and glance at your speedometer, since the new road is probably much slower
After a long stretch at highway speed, 40 mph feels like crawling and drivers routinely leave a ramp far too fast. Ramps often carry a lower limit of their own, and the road you are joining is unlikely to allow 55 mph, so read the signs and glance at your speedometer.
6. What does it mean to drive 'within the range' of your headlights at night?
Correct answer: Driving slowly enough to stop inside the roughly 350 feet your lights reach
Darkness shrinks how far ahead you can see, and your beams throw light roughly 350 feet down the road. Travel faster than you can stop inside that stretch and you will reach a hazard before you can react to it. Slow further on unfamiliar or twisting roads.
7. Why do some New York highways post a minimum speed?
Correct answer: Because vehicles that crawl along break up the flow and create danger
Traffic works best when everyone moves at a similar pace. A driver well below the pace of the road forces others to brake and swerve, which can be every bit as hazardous as one who speeds. Even where no minimum is posted, crawling along creates risk.
8. The entrance ramp you are on is too short to let you build up to highway speed. What is the safest way to join the traffic?
Correct answer: Stop, wait for a wide gap, then pull out and accelerate hard
A short ramp gives you no room to match the pace of the highway, so it is safer to wait at the end for a wide opening and then get up to speed quickly once you are in it. Reversing on a ramp is dangerous and never an option.
9. Another driver is following you too closely (tailgating). What is the safest response?
Correct answer: Increase the space in front of you and, if safe, let them pass
You cannot control the tailgater, but you can protect yourself. Leave more room ahead so you can slow gradually instead of braking hard, and move over or let them pass when it is safe.
10. You are overtaking a slower car and would have to exceed the posted limit to finish the pass quickly. What does the law say?
Correct answer: The limit still applies — you may not break it in order to pass
There is no exemption for passing. If you cannot complete the maneuver without breaking the limit, the gap is too small, and you should stay behind until you have room to pass legally.
