Summary

Primary Sponsor: George M. “Marc” Keahey
Democrat
Session: Regular Session 2010
Title: Trucks, weight limit for vehicles equipped with a functioning auxiliary power or idle reduction technology increased, Sec. 32-9-20 am'd.
Summary: SB288 allows trucks with a functioning auxiliary power unit or idle reduction technology to carry up to 400 extra pounds in weight limits, if they meet proof and functionality requirements.
What This Bill Does
The bill amends Alabama's weight restrictions to add an up-to-400-pound boost to gross, axle, tandem, or bridge weight limits for vehicles that use a functioning auxiliary power unit (APU) or idle reduction technology. To qualify, the operator must provide written proof of the APU’s weight and certify that the idle reduction technology is fully functional at all times, with the proof available to law enforcement; the allowed extra weight cannot exceed 400 pounds or the proven weight, whichever is less. The increase applies to state highway weight limits and is to be enforced under existing procedures and tolerances, while other unrelated weight and size rules, as well as certain exemptions, remain in place. The act takes effect immediately after the Governor signs it.

Who It Affects
Truck operators and trucking companies that install and use an auxiliary power unit or idle reduction technology, who may gain up to 400 additional pounds in permissible vehicle weight if they provide proof and maintain functionality.
Law enforcement, the State Transportation Department, and other agencies responsible for enforcing weight limits, who must verify the provided proof and ensure compliance with the new limit.
