An eight-week campaign has been launched by police and councils in Kent to cut down on the number of accidents involving cyclists and motorbike riders.
Between 2010 and 2012, there were 2,000 casualties on the county's roads.
Of those, 27 were fatal accidents.
Road users are being urged to "Think Bike" or "Biker Think", with highly visible boards being put up to remind people to be aware of each other.
Motorcyclists make up less than 1% of road users but they account for almost a quarter of all road deaths every year in Kent and Medway.
Medway Councillor Phil Filmer said:
We ran our version of the Think Bike campaign last year and it was very successful with a lot of feedback from the public saying the roadside boards did make them think and look more vigilantly for 2 wheeled road users.
For the second year running we have extended the campaign to include cyclists as there is a worrying trend in the number of collisions involving people on bikes and we are keen to get the message out that drivers should be aware of everyone on two wheels.**
