These are some of the signs that you may see at a bridge over a railway.
As you approach a railway bridge you must obey any road signs and roadway markings.
Examples of weight restriction signage
Maximum Gross Weight Maximum Axle Weight
If any axle on your vehicle exceeds this weight, you cannot proceed beyond the sign.
The total weight of your vehicle including its load must weigh less than this to safely proceed beyond the sign.
Other signs
Maximum Gross Weight (Safety) Maximum Vehicle Width
Your vehicle must be narrower than the width shown to be permitted to proceed beyond the sign.
If your vehicle’s gross weight exceeds that specified on the sign, you cannot proceed beyond the sign.
Road tunnel signs
These lane control signs are found above each traffic lane at, or on, the approach to the entrance to a road tunnel and at regular intervals inside a road tunnel. When the signs are operational, the amber lights at the top and bottom will flash in turn.
