The eight men, aged between 30 and 55, face charges under Section 63(4) of the Road Traffic Act 1961 for speeding. The penalties involvedThe offence of speeding under the Road Traffic Act carries a fine of up to S$1,000, imprisonment of up to three months, or both. Heavy vehicles found exceeding their regulated speed limits are also required to undergo inspection to verify that their speed limiters are functioning correctly. Expanding speed limiter requirementsThe eight cases arise against Singapore’s progressive expansion of mandatory speed limiter requirements to cover more heavy vehicles. Heavy vehicles with a maximum laden weight (MLW) exceeding 12,000 kg are required by law to be fitted with working speed limiters.
