Truck owners are allowed to tint the windshields and side windows of a truck’s cab, which could protect drivers from harmful sunlight, the International Window Film Association said.
IWFA cited a letter it received in October from the Federal Motor Carrier Safety Administration, in which the agency said that regulations allow window tinting, as long as at least 70% of the light transmission gets through the window.
“The clarification represents information that impacts millions of truck drivers who drive many hours at a stretch in ‘big rigs’ weighing more than 26,000 pounds,” Darrell Smith, IWFA’s executive director, said in a statement.
Skin cancer is more prevalent in the left arm and left side of the face, likely due to increased exposure to harmful ultraviolet A light from driving, IWFA said.
IWFA sought FMCSA’s guidance because law enforcement officers sometimes believe tint is never allowed on truck cab windows, the association said.
