Pol Maj Gen Jiraphat Phumijit, deputy commissioner of the Metropolitan Police Bureau, said the commissioner, Pol Lt Gen Charnthep Selavej, had ordered the 88 stations to strictly enforce the time ban. 
He said if truckers continued to enter inner Bangkok during the banned hours, the bureau may be forced to consider banning trucks from certain routes. 
Currently trucks with at least ten wheels are banned form inner Bangkok from 6-10am and 3-9pm. Six-wheel trucks are banned from inner Bangkok from 6-9am and 4-8 pm. 
Violators will be subject to a fine of Bt1,000. 
All trucks are also banned from using the aged Krung Thon Bridge, Jiraphat added.
