Louisiana Truck Lane Restrictions
Louisiana has no statewide truck-lane law, but the I-10 Atchafalaya Basin Bridge is a hard exception. Across its ~18 miles commercial trucks must run the right lane, left only to pass, at 55 mph, posted with 'Trucks Right Lane Only' signs and enforced by camera with doubled fines (La. R.S. 32:268). Everywhere else it's the general keep-right rule.
