Earlier this year the government warned travelers to be wary of fake traffic police, and two Norwegians recently found out why. They were robbed of their new car and all their belongings by three bandits in police uniforms who stopped them on the highway between Sofia and the Black Sea port of Varna as if for a routine check. How would you know if police flagging you down are bonafide? The best bet is to scrupulously obey all traffic laws and keep driving to a busy area before stopping for questioning.
