Pennsylvania Truck Lane Restrictions

Which lanes a truck can use in Pennsylvania

Pennsylvania keeps trucks over 10,000 pounds out of the left lane on any limited-access highway with three or more lanes each way (75 Pa.C.S. § 3313). You can use it only to set up a legal left turn. On any limited-access road with two or more lanes, keep right except to pass. It is a summary offense, with a base fine of about $25 plus court costs.

Roads, exceptions, and signs

• Where it applies: Limited-access highways (interstates and freeways) with 3+ lanes in the same direction, statewide.
• Some corridors post 'Trucks Use Right Lanes,' but the rule is statutory and applies whether or not a sign is present.
• General rule: 75 Pa.C.S. § 3313(a)-(b) (right lanes on limited-access highways except to pass) and § 3301 (general drive-on-right).
• The 10,000-lb trigger and the 3-or-more-lane limited-access condition are verified against the statute text. The left-turn carve-out is the only exception the statute names for the truck provision.

What a lane violation costs

Summary offense. Base fine about $25 plus court costs, so the total owed runs higher.
