Here is some of the signs I've seen in India:
Beware of unattended luggage, briefcase without owners or even an innocent looking toy or transistor. If you see any of these please contact the police immediately. Your prompt action could help save hundreds of lives.
Rohar Police, a friend in need.
Badly built bridge drive carefully.
Speed thrills, but kills.
Speedest English speaking course!
Dont throw rubbish God will be angry.
From January to December, there is safety to remember.
Left is right.
