The National Transport and Safety Authority (NTSA) has identified seven road safety violations that will be targeted in its renewed enforcement campaign after impounding 13 vehicles during a night-time operation.
In a statement, the authority said the violations were detected during a multi-agency safety compliance operation conducted along the Southern Bypass on Wednesday night.
"Last night, the inter-agency team conducted a safety compliance check along the Southern Bypass, during which thirteen (13) motor vehicles were detained," NTSA said.
The offences flagged included driving under the influence of alcohol, operating vehicles with expired driving licences, using vehicles with expired inspection stickers and driving without valid insurance.

Other violations involved breaching insurance conditions, faulty headlights and cracked windscreens.
NTSA said night-time enforcement was a priority because evening and late-night hours are among the most dangerous periods for road users, necessitating stricter checks to curb risky driving behaviour.
The authority reminded motorists to ensure their vehicles have valid inspection stickers and insurance. Drivers must also possess valid driving licences and, where applicable, Public Service Vehicle (PSV) badges.
The crackdown is part of the Msimu Bila Ajali Usalama Barabarani campaign, under which NTSA collaborates with law enforcement agencies to conduct daytime and night-time inspections along major transport routes.
"We are also checking whether vehicles comply with speed limits and whether installed speed limiters are functioning correctly and continuously transmitting data to the Intelligent Road Safety Management System (IRSMS)," NTSA added.
Motorists have been directed to access the upgraded IRSMS portal at irsmowners.ntsa.go.ke and link their vehicles to licensed speed limiter vendors.
The authority has also provided a user guide at ntsa.go.ke/irsms and an email address, irsmsqueries@ntsa.go.ke, for motorists seeking assistance with the process.
Long-distance public transport operators are expected to meet documentation requirements, including carrying passenger manifests, maintaining driver logs to monitor driving hours and displaying valid vehicle inspection stickers.
NTSA further warned operators against carrying passengers or cargo beyond their authorised capacity, urging them to observe the prescribed passenger limits and load weights.
Drivers will also be required to undergo breathalyser tests as part of efforts to detect and deter drink-driving.
Meanwhile, passengers have been urged to wear seatbelts throughout their journeys to minimise the risk of serious injuries or fatalities in the event of a crash.
The authority also cautioned motorists about fraudulent messages purporting to communicate official traffic violations.
"Official speed violation notifications are sent exclusively through SMS under the sender ID NTSA," the authority warned.
Drivers have been advised to ignore suspicious messages from numbers claiming to represent NTSA and report them promptly.
