This question was found in context to a chapter about momentum and Newton's Laws...so you can think along that direction. And it isn't mentioned that the bridge is sloped, which is why I cannot find the answer.

If the bridge has an arched back, the truck's speed would provide some centrifugal force. Meaning the truck would be lighter on its tires. Going slower decreases this effect.

Whenever certain vehicles (depending on size) enter onto a bridge, they are going higher into the air as the ramp is extending. Once the vehicle is on the bridge, they are no longer driving in the same air thickness as before. This is why the air in the mountains are so drastic. The air is thinner and less dense. Anyway, the air difference has a different effect on moving objects, causing more slow movement.

because of drag force and its gravity.
