The issue was discussed in the State Transport Authority (STA) meeting last month and the traffic police has been asked to justify its objection with details of accidents attributed to distraction caused to motorists, said a senior government official.
The Delhi Traffic Police will provide the details within one month. Till the time, the approved proposal will be kept in abeyance.
A senior Delhi Traffic Police officer admitted its objection to the proposal although there are no instances that could be cited in favour of opposition to displays on right side of the buses.
"There are no instances that we can site but even internationally, objections have been raised on this kind of advertising. Many experts have called it a "security risk" for motorists," the officer said.
The 'guideline on display of advertisement on public service vehicles, 2014', allowed displays only on left and rear sides of the buses.
DTC cited various examples of state transport undertakings like BEST in Mumbai, UP, Haryana and Himachal Roadways, besides Metro feeder buses and HoHo buses of Delhi Tourism, where displays on right sides of the vehicles is allowed.
Considering the DTC request, STA amended the advertisement guidelines, in May 2016, permitting display of advertisements on right sides of the buses.
In October 2016, however, the Special Commissioner of Delhi Police (Traffic) who is also a member of the STA Board, registered his objection that display of advertisements on right side of the public vehicles will be "a source of distraction" for the motorists that may lead to road accidents.
The officer said that advertisement display on right side should not be allowed and the amended guideline needs to be restored to its original prescription of advertisements only on left and rear sides of the vehicles.
