     § 3313.  Restrictions on use of limited access highways.
        (a)  General rule.--The department may regulate or prohibit
     the use of any limited access highway by any class or kind of
     traffic which is found to be incompatible with the normal and
     safe movement of traffic.
        (b)  Traffic-control devices at entrances.--The department,
     when adopting any prohibition under this section, shall erect
     and maintain official traffic-control devices at the entrances
     to the limited access highway on which the prohibitions are
     applicable and when in place no person shall disobey the
     restrictions stated on the devices.
        (c)  Motorcycles.--Except on busways in counties of the first
     or second class, motorcycles may be operated upon any limited
     access highway in an urban district in a lane specified for
     multioccupant vehicles or car pools, except where the department
     can demonstrate that such use will create a safety hazard.
        (d)  Driving in right lane.--
            (1)  Except as provided in paragraph (2) and unless
        otherwise posted, upon all limited access highways having two
        or more lanes for traffic moving in the same direction, all
        vehicles shall be driven in the right-hand lanes when
        available for traffic except when any of the following
        conditions exist:
                (i)  When overtaking and passing another vehicle
            proceeding in the same direction.
                (ii)  When traveling at a speed greater than the
            traffic flow.
                (iii)  When moving left to allow traffic to merge.
                (iv)  When preparing for a left turn at an
            intersection, exit or into a private road or driveway
            when such left turn is legally permitted.
            (2)  Unless otherwise posted, no vehicle or combination
        over 10,000 pounds may be driven in the left-hand lane of a
        limited access highway having three or more lanes for traffic
        moving in the same direction except when preparing for a left
        turn at an intersection, an exit or into a private road or
        driveway when such left turn is legally permitted.
