100.This section sets out new powers of inspection, to be available where the Secretary of State has reasonable grounds for suspecting that a regulated rail vehicle does not conform with those provisions of RVAR with which it is required to conform. The section also grants similar powers of inspection following the issuing of notices under section 47E(1) or (4). The Secretary of State may authorise an ‘inspector’ to examine and test such vehicles and, for the purposes of exercising these powers, the inspector is empowered to enter premises at which he believes the vehicle to be kept, and to enter the vehicle. If an inspector is obstructed in the exercise of these powers the Secretary of State may, in certain circumstances, impose a penalty on the operator.
