Truck fuel tanks can now be filled to the brim, not just 95%

The US Federal Motor Carrier Safety Administration proposes removing a rule that limits how much fuel commercial truck tanks can hold. This means truck drivers will be able to fill their tanks completely, rather than leaving 5% empty space.

For over 50 years, federal rules required truck fuel tanks to have a 5% empty space, supposedly for safety. This rule made it harder for truckers to maximize their range between fuel stops. Removing it means fewer stops and potentially lower operating costs for trucking companies.
