Example Signing for Left Lane Restriction Plaques
Advance warning using the AHEAD plaque over the NO TRUCKS LEFT LANE sign should be used in advance of the restricted truck lane. The BEGIN plaque over the NO TRUCKS LEFT LANE sign and the END plaque over the NO TRUCKS LEFT LANE sign should be used at the restriction limits. If the restriction is not 24 hours a day, 7 days a week, then the restricted times should be mounted below the NO TRUCKS LEFT LANE sign. The typical plaques used in conjunction with the NO TRUCKS LEFT LANE sign are shown in Figures 5-10, 5-11, and 5-12.
