Are trucks allowed to use compression braking at all times?

Yes, it is always allowed
No, it is prohibited unless for safety
Only in residential areas
Only on highways

The correct answer is: No, it is prohibited unless for safety

In Delaware, the use of compression braking, also known as engine braking, is regulated due to noise concerns and safety considerations. It is generally prohibited in certain areas, especially where it may affect residential communities and create disturbances. However, the use of compression braking is permitted in situations where safety is a concern, such as when a driver needs to slow down or maintain control of the vehicle, especially on steep declines. This regulation balances the need for safety while addressing community concerns about noise. The other options do not accurately reflect the restrictions placed on compression braking. Allowing it at all times would ignore the local regulations aimed at minimizing noise pollution. Limiting it only to residential areas or highways does not encompass the safety exceptions that are incorporated into the law.
