THE unruly conduct of some PSV drivers has led to the suspension of their licence, says LTA spokesman Iliesa Sokia.
"They top the list of most road offenders in the country," he said.
"We receive complaints from members of the public almost every day on the way they are treated by public service vehicle drivers."
Mr Sokia said the authority did not take these complaints lightly.
"They are there to serve the travelling public.
We issued those licences so they could carry out their services and we expect them to adhere to the laws set out for them.
"This is simple customer service and they have a duty to the members of the public."
Mr Sokia said PSV licence holders continue to be cited for traffic infringements.
"Some of them have 20 traffic infringement notices (TIN) and when they reach that stage they are classified as dangerous drivers.
"When they get more than 20 TINs, their licences are suspended.
"Some of them get six months suspensions, while others lose theirs for a year."
In February, LTA revealed PSVs in the West were the most notorious traffic offenders. 116 drivers had show-cause cases.
Of these 12 were served with about 40 infringement notices, 13 were on last warning and 20 classified as dangerous after accumulating about 20 infringement notices.
