Vehicles on Linda Mar Blvd.

Didn't there used to be a weight limit on vehicles on Linda Mar Blvd? Yesterday I saw one of the trucks hauling 8 cars on the trailer. Why did it need to be on Linda Mar and turning down Adobe? I am also surprised at the logging trucks dropping tree trunks at the nursery on Linda Mar Blvd.  Linda Mar Blvd. is bad enough without all this added weight, or am I wrong? I thought there used to be a sign down near the LM Shopping Center posting a weight limit. Maybe they took it down when all those dump trucks were flying up and down the blvd. for the tunnel or whatever that was going on.
