CHP impounds semi for speeding and suspended Motor Carrier Permit

The California Highway Patrol impounded a semi truck on southbound SR-99 near Hammett Road after an officer caught it traveling at 70 m.p.h. in the fast lane, according to CHP's Modesto Division. During the traffic stop, the trooper discovered the truck's Motor Carrier Permit was suspended, triggering an immediate out-of-service order and impound. California law caps commercial vehicle speeds at 55 m.p.h., a limit that applies to semis, three-axle vehicles, and tractor-trailers. The rules also restrict these vehicles to the right lane except when passing another vehicle or preparing for a left turn at an intersection or private entrance. The enforcement action highlights a compliance gap among some operators. A truck traveling 15 m.p.h. over the limit while operating with a suspended permit faces serious consequences: downtime, impound fees, and potential driver qualification issues. CHP reminded carriers and drivers that current licenses, permits, and documentation must be in place before any trip, and that speed regulations exist to protect all road users.
