These include, under subsection (1)(a)(i) of section 88, where the driver has held a licence to drive that class of vehicle and, under subsection (1)(b)(i), where the Secretary of State has received a qualifying application by the driver for a licence to drive that class of vehicle. 47 This section prevents High Risk Offenders from having entitlement to drive by virtue of section 88 of the RTA, whilst awaiting the outcome of medical enquiries relevant to an application for the return of a licence following a period of disqualification. This will ensure that those who, by the nature of their offending, have been identified as presenting a greater risk of being medically unfit to drive are prevented from driving until the Secretary of State is satisfied that they are fit to do so.
