The California Highway Patrol has special messages for truckers during the Thanksgiving period. The CHP’s Commercial Vehicle Section is sending updates to commercial truck drivers to notify them about hazards, closures, and enforcement operations in high-crash areas around the state. The messages are 25 words or less and are sent through truck drivers’ Electronic Logging Devices which are required for drivers to track their hours. The Highway Patrol’s Maximum Enforcement Period runs until 11:59 p.m. Sunday.
