Unregistered vehicles are still able to enter Malaysia in the mean time as the Government is still working on the activation of its Vehicle Entry Permit (VEP) system which will resume in due course, according to Road Transport Department (RTD) website.
Since 1 June, the VEP system, which would be applied later to the other 10 road entry checkpoints into Malaysia, from Thailand, Brunei and Indonesia, has been activated at the two land entry points in Johor at the Causeway and at the Second Link.
Before entering Malaysia, Singapore-registered vehicles must register with Malaysia’s Road Transport Department before they are able to enter the neighboring country.
A one-time fee of RM10 (S$3.30) will be charged to install a radio frequency identification (RFID) electronic chip. This ID will be valid for five years. As of July 2016, A total of 144,000 vehicles had registered for the VEP.
A road charge will also come into effect on 1 November. Singapore-registered vehicles entering Malaysia are required to pay a RM20 (S$6.60) levy.
The Government has stated that Singapore-registered vehicles which are not registered with a VEP, will be refused entry into the country once the system is fully implemented.
