Unless otherwise posted, the speed limit for cars in a residential area is A: 25 miles
per
hour
B: 30 miles per hour.
C: 35 miles per hour.

The answer is A (25 miles per hour).

the warning light flashes for a second or two when the engine starts. if it stays on, there's must be something wrong with the coolant. you should never dare to continue driving when the light is on. pull over as soon as possible and shut the engine off.

hope this is what you're talking about
