A revised traffic regulation that took effect on New Year's Day and is being called much too harsh by some drivers.

A key complaint is that the revised rule raises the stakes for drivers who run yellow lights. Under the revision, running a yellow light would be treated the same as a running a red light and cost drivers a deduction of six points - half the 12-point limit - from their driver's licenses. Formerly, only three points were deducted.

Drivers also complained that the extra care it forces them to take to avoid running yellow lights can easily cause rear-end collisions.
