True or false: A force-to-weight ratio over 4:1 earns a vehicle a good rating in a roof strength test.

The statement is true because a force-to-weight ratio of over 4:1 indicates that the vehicle can withstand more than four times its weight in force during a roof strength test. This ratio is a critical metric used in evaluating the structural integrity of a vehicle's roof in rollover situations. A higher force-to-weight ratio signifies a higher level of safety for occupants, suggesting that the vehicle's roof is strong enough to prevent crushing during a rollover. Thus, achieving a ratio above 4:1 typically earns the vehicle a favorable rating in this assessment, as it correlates with improved crashworthiness and occupant protection in accidents.
