346.10(4) (4) The operator of a vehicle shall not overtake and pass any other vehicle proceeding in the same direction when the view is obstructed upon approaching within 100 feet of any bridge, viaduct or tunnel unless the roadway is of sufficient width for 2 or more lines of vehicles to lawfully proceed simultaneously in the direction in which such vehicle is proceeding or unless permitted or directed by a traffic officer to so overtake and pass.

346.13(3) (3) Notwithstanding sub. (2), but subject to sub. (4), when lanes have been marked or posted for traffic moving in a particular direction or at designated speeds, the operator of a vehicle shall drive in the lane designated.

346.14(2)(b) (b) This subsection does not apply upon any lane especially designated for use by motor trucks or by truck tractor-semitrailer or tractor-trailer units nor does it apply when overtaking and passing another vehicle, but the fact that the operator of any vehicle or combination of vehicles mentioned in this subsection follows the preceding vehicle more closely than 500 feet for one mile or more or follows more closely than 500 feet when the preceding vehicle is moving at the maximum speed then and there permissible for such following vehicle is prima facie evidence that the operator of such following vehicle is violating this subsection.
