Visitors urged to respect everyday Island life
This years TT road safety message is highlighting people who bikers might meet if they become a road casualty.
The strap lines are "the professional people you don't want to meet", and "who will you leave behind when you go speeding off?"
Ferry passengers will be greeted with the messages as they enter the Island.
Chief Constable Gary Roberts has warned those who break the law, his officers are more than ready to take the appropriate action.
Visitors are also reminded that while the festival takes centre stage for two weeks, everyday life in the Isle of Man continues.
