During the hours of 3pm -7pm the 2 far left lanes of the Bay Bridge toll plaza are carpool lanes (3 or more passengers only). During these hours a CHP motorcycle cop will usually sit in the shoulder after the toll plaza gate looking for vehicles going through the gate faster then 25mph OR looking vehicles cars who have only 1 or 2 passengers in them going through the carpool gate because they dont want to pay the $3. Beware! Everytime I pass this area around this time I either see the motorcycle cop there or see someone pulled over before the bridge incline.
