Hanoi drivers are expressing confusion and anxiety over a new regulation requiring a minimum safe following distance of 55 meters. Experienced driver Nguyen Thanh Tuan admits difficulty accurately judging this distance visually, creating uncertainty on the road. The primary concern is the risk of receiving automated traffic tickets (“trát phạt nguội”) if other vehicles unexpectedly change lanes into the designated safety zone. Drivers fear being penalized despite diligently attempting to comply with the new rule. This regulation aims to improve road safety by reducing rear-end collisions, but its practical application is proving challenging. The lack of clear guidance and difficulty in visual estimation are contributing to driver frustration and potential enforcement issues. It remains to be seen how effectively this rule can be implemented and enforced.
