This time a double decker bus in Croydon.
There have been a number of incidents with buses, trains, trams, boats and even planes, where drink is said to have been involved. Surely it is time to breathalyse or drugalyse the drivers / pilots, and I do not mean random tests. I mean compulsory checks before any shift begins.
The tests take seconds to administer and the results are virtually instant. There can be no excuses for not doing them in order to keep passengers / customers safe.
