Final answer:
The driver towing a trailer keeps to the right on a three lane highway because the right lane is designated for slower-moving vehicles, while the left lane is for faster-moving ones. The middle lane has no special designation for vehicles without trailers, and the right lane doesn't necessarily provide more space for maneuvering.
Step-by-step explanation:
On a three lane highway, a driver towing a trailer typically keeps to the right for several reasons related to traffic regulations and safety. Among the options provided, the correct answer is that The right lane is designated for slower-moving vehicles. This is generally true because traffic laws often state that slower-moving traffic should keep to the right to allow faster-moving vehicles to pass on the left. In contrast, the left lane is designated for faster-moving vehicles, which include cars that are overtaking or traveling at higher speeds. There is no specific designation for the middle lane for vehicles without trailers, nor does the right lane provide more space for maneuvering with a trailer.
Regarding the given scenarios: If the car is traveling in the furthest lane from the rabbit, the rabbit's ability to cross all 3 lanes of the freeway safely depends on many variables, including the speed and proximity of other vehicles, not just the lane of the one car. A car moving on a straight road at a constant speed in a single direction suggests uniform motion, which is one of the features of motion described in physics. If you notice a trailer bouncing up and down slowly, it might suggest that the trailer is nearly empty; a heavily loaded trailer would typically have less bounce due to the added weight dampening the motion.
