Once the brakes have been applied, about how many feet does a car which was going 70 mph travel before it comes to a stop?
About 233 feet of braking distance. Total stopping distance, including the 1½-second think-and-react interval, is about 387 feet on dry, level pavement with good brakes.
About how many feet will the average driver going 50 mph travel from the moment he sees danger until he hits the brakes?
About 110 feet — the 1½-second perception-and-reaction distance at 50 mph.
What is the state speed limit for automobiles in urban districts?
30 mph, unless a different limit is posted.
Does a posted speed limit of 55 mph mean that you may drive 55 mph on that highway under all conditions?
No. The basic speed law still requires a speed that is reasonable and prudent for conditions — even if that is slower than the posted limit.
When following another car, what is a good distance at which you should follow behind?
At least 2 seconds at 30 mph or less in good conditions; at least 4 seconds above 30 mph. Increase in poor conditions. Four seconds is best practice for new drivers.
If a child runs into the road 45 to 50 feet ahead of your car, what is the highest speed from which you can stop with good brakes without hitting him?
About 20 mph. At 20 mph the total stopping distance is about 63 feet.
