The state Senate has passed a bill backed by the union representing city bus drivers that would prevent them from being arrested at the scene of an accident.

The Transport Workers Union says under the proposed law, a bus operator who is not reckless and cooperates with police would not be handcuffed or thrown into a holding cell. They say the driver could still be charged with a misdemeanor after an investigation.

The union has been up in arms since the city's Vision Zero law was passed because several bus drivers have been arrested in deadly crashes.

The advocacy group Families for Safe Streets strongly opposes the bill. They say it's unfair to give bus drivers special treatment.

The bill still needs to pass the Assembly.
