Rear seatbelt checks on expressways since Sept 19 — fair law or fining a design flaw?

Police have been strictly enforcing the rule that every passenger on an expressway, back seat included, wears a seatbelt. By early October nearly 3,000 people were already facing legal action, with a Rs 1,000 fine that can land on the owner, driver and passenger separately. Police point to a recent multi-vehicle pile-up where belted passengers walked away with nothing worse than a fright. The case for: Rs 1,000 and a bit of discomfort is nothing against what a seatbelt actually buys you in a crash, and nobody buckles up voluntarily if there's no real enforcement behind the rule. The case against: plenty of older cars, hired vans and buses still don't have working rear belts fitted at all, so some people are getting fined for a gap in the vehicle, not their own carelessness, with no quick way to fix it before their next trip. Have you been stopped for this on an expressway, did your car even have a rear belt to check, and does Rs 1,000 actually change anyone's behaviour? ඔබේ රථයේ පසුපස සීට් බෙල්ට් තියෙනවද?
