Netizens are criticising the use of speed cameras on superhighways in the Lamphun-Lampang area, especially in Doi Khun Tan, where the speed limit is between 50 and 90 kilometres per hour. Netizens say that this hilly area demands strong driving skills and the speed rule is unreasonable.

Expressway Authority of Thailand (Exat) will install additional cameras to detect speeding vehicles as well as vehicles running on the road shoulder on expressways.
