Sussex police are banning dangerous taxis, limo and buses while ferrying people in Brighton and Hove.
A joint operation between Sussex Police, Vehicle and Operator Services Agency and Hove City Council has seen 43 vehicles stopped in one day.
Some of the vehicles were in such a bad condition that they were immediately prevented from being used to carry passengers.
The vehicles were stopped from 7pm-11pm on Saturday, August 10.
Some of the stopped vehicles had broken headlights, damaged bodywork or were not carrying a driver's badge.
Chief Inspector Natalie Moloney said: "Every person who gets into a taxi or private hire vehicle should feel safe in the knowledge that they are not being put in danger. We will continue to work closely with other agencies to keep all road users as safe as possible."
Police are investigating after several vehicles were severely damaged after a fire at Havant, Hampshire.
The Fire Service were alerted to the fire at 2.45am this morning and seven vehicles have been burnt out or severely damaged as a result of the blaze.
It is believed a hole was cut in fencing to gain entry to the compound sometime after 2am.
We are aware of previous reports of damage to Andicars vehicles and looking into the possibility that they may be connected to this most recent incident. At this stage we have no evidence to confirm they are linked."
