Step-by-step explanation:
The guidelines regarding speed for responding units, such as ambulances, vary depending on the jurisdiction and the specific circumstances. In general, emergency vehicles are allowed to exceed the speed limit and may use sirens and flashing lights to alert other drivers. However, they are still required to drive with due regard for the safety of others.
For example, in the United States, most states have laws that allow emergency vehicles to exceed the speed limit as long as they exercise caution and do not endanger others. In some cases, they may be required to slow down or stop at intersections to ensure safety.
Ultimately, the main goal of responding units is to reach their destination quickly and safely, while minimizing the risk to themselves and others on the road.
