All taxi licensing authorities can now apply for enhanced crb checks before issuing licences to taxi and private hire drivers, enabling authorities to find out if someone has been barred by the ISA from working with children or vulnerable adults before issuing a licence.

It is understood that these changes will provide reassurance to women and other vulnerable customers who use the services and has been welcomed by groups campaigning for women’s safety.  Up until now, only those drivers regularly collecting children or vulnerable people had been eligible for enhanced checked but the change will standardise the practice for all drivers.

Tighter checks on taxi drivers are only a part of a radical overhaul of the criminal records system.
