People argue that heavy trucks require longer braking distances for any given speed, and lower truck speeds help equalize the stopping distance. On the other hand, opponents of lower truck speed limits have suggested that the differential speeds increase speed variance and therefore have a negative impact on highway safety. Our research demonstrates that it is likely that both of these arguments are correct.
