Why would a national speed limit be effective during the oil crisis in 1973?

People were speeding to the gas stations.
More accidents meant more energy used.
It would conserve energy by limiting fuel consumption.
There was no speed limit until this time.

Respuesta :

The answer would be the third option or "it would conserve energy by limiting fuel consumption." This is because the speed limit was limited to 55 miles per hour, so there would be no excess speeding and less fuel being burned from the lower speeds. i hope this helps :)
