THE Land Transport Authority receives at least between eight to 10 complaints daily against public service vehicle operators.
LTA chief executive Naisa Tuinaceva said some PSV licence holders continued to disrespect the public and portrayed rude behaviour.
"We have received complaints regarding rude behaviour, impatient attitude, unkind service, over charging, using mobile while driving and many more.
"LTA receives between eight and 10 complaints every day about PSV drivers and I am extremely concerned with this type of attitude because it doesn't paint a good picture.
"Most of the complaints are about the attitude of drivers that had not changed over time.
"Complaints received concern bus drivers who impatiently try to disembark passengers and rush those who are trying to get onto the bus."
Mr Tuinaceva said some taxidrivers decided which route to take instead of taking the shortest one available.
"One of the main concerns is taxidrivers who do not provide service to physically-impaired people, our elderly and those who need assistance and this is really not the way LTA expects them to behave," he said.
"Bus drivers also don't have the courtesy to stop and pick these citizens."
