A DVSA crackdown has found that one in 10 vehicles had the most dangerous mechanical issues.
The news comes following a day of action by DVSA, National Highways and also local police forces.
The defects covered a range of components on trucks that were subjected to roadside checks.
For example, problems with steering, suspension and wheels were reported.
In addition, tyres and brakes were also found to be not roadworthy in some cases.
All are parts that affect driver’s control, therefore could have resulted in a serious injury, argues DVSA.
The DVSA crackdown, which happened on 29th September, targeted vehicles from Edinburgh to Dover and Glasgow to Plymouth.
Meanwhile, there were 83 deliberate or negligent traffic offences recorded.
