| Registrar may refuse to grant vehicle entry permit |
| 21. The Registrar or an authorised officer may refuse to grant a vehicle entry permit or may cancel a vehicle entry permit already granted if the vehicle fails to meet the noise emission standards for the time being in force, or emits smoke or visible vapour, or if he has reason to believe that the motor vehicle to which the application or permit relates has been or is intended to be used for any unlawful purpose. |
