You are driving a vehicle that can safely be driven at 55mph on an open road, but traffic is now heavy moving at 35mph though the speed limit is 55mph. The safest speed for your vehicle is?

25 mph
35 mph
45 mph
55 mph

The correct answer is: 35 mph

In this scenario, the safest speed for your vehicle is 35 mph. When driving in heavy traffic, it's important to match the speed of surrounding vehicles to maintain safety. Although the speed limit is 55 mph and your vehicle is capable of driving at that speed, traffic conditions dictate a slower pace. Driving faster than the flow of traffic can lead to dangerous situations, such as collisions or abrupt stops. Maintaining a speed that matches the traffic flow helps to ensure that you can react appropriately to any changes in the movement of other vehicles around you and reduces the risk of accidents. Consequently, even if you are technically allowed to drive faster, the safest course of action is to drive at the speed of the traffic, which in this case is 35 mph.
