No changes to the window tint regulations

| Wednesday, April 04, 2012

Even though a recent public relations campaign has alluded to a DOT “clarification” on window tinting in semi trucks, the fact is that nothing has changed.

The regulations governing window tint on side windows of big rigs – 393.60 – remains as it has been for quite some time. The regulation states:

(d) Coloring or tinting of windshields and windows. Coloring or tinting of windshields and the windows to the immediate right and left of the driver is allowed, provided the parallel luminous transmittance through the colored or tinted glazing is not less than 70 percent of the light at normal incidence in those portions of the windshield or windows which are marked as having a parallel luminous transmittance of not less than 70 percent. The transmittance restriction does not apply to other windows on the commercial motor vehicle.

Similarly, while the regulation has not changed, neither has the guidance relating to it.

In short, as long as you have tint (colored or not) that complies with 393.60, you have been and will continue to be legal.
