Vehicle owners may modify their vehicles for many reasons. Whatever the
reason may be, be it to improve the vehicle’s performance or to create a
distinctive or customised appearance, it is important to ensure that the
modifications meet the requirements of the Land Transport Authority (LTA).
LTA has a set of guidelines for vehicle modifications to ensure that
standards for road safety and vehicle exhaust gas and noise emissions are
not compromised, for the benefits of vehicle owners, other road users and
our environment.
