The Local Government Association (LGA) has warned that the relaxing of minicab licensing rules carries a risk of danger to the public.
The Deregulation Bill, which is currently going through Parliament, would make it "impossible" for councils to thoroughly monitor who acquires a minicab licence.
The legislation could also mean that minicab drivers are able to challenge reviews of their licences more easily after committing traffic offences, by claiming another driver was at fault.
Tony Page, LGA licensing spokesman, says taxi and private hire passengers should be able to use these services safe in the knowledge that drivers have undergone background checks and have met certain safety standards.
He added that the new bill could undermine the LGA's successful reinstatement of enhanced criminal record checks on drivers.
A spokesman for the Department for Transport said that the Deregulation Bill will not put taxi passengers at risk and said that drivers will still need to pass routine background checks.
He added that the measures have been tested in London and have made life easier for both drivers and passengers.
