A look at the rules and regulations governing American truck drivers and sleep

Trucks are driven near the Ports of Long Beach and Los Angeles, the busiest port complex in the US, on September near Long Beach, California.

On Monday, New Jersey authorities said the Walmart trucker charged in the fatal crash that involved 30 Rock star Tracy Morgan reportedly hadn't slept in 24 hours prior to the accident that killed one and injured several others.

The high-profile crash comes only days after a Senate panel approved a proposal backed by the American Trucking Associations (ATA) to roll back new rules, first proposed in 2010, forcing truck drivers to pull over and log a minimum number of hours for rest.
