More than half (55%) of motorists were often "surprised when a cyclist appears from nowhere", the AA/Populus survey showed.
The results came as the AA and the AA Charitable Trust, with support from British Cycling and the Motorcycle Industry Association, launched a national Think Bikes awareness campaign.
Initially, one million free stickers will be distributed to drivers as a reminder to do a 'double-take' in their mirrors for cycles and motorcycles in blind spots. It is suggested that the cycle sticker is placed on the passenger's side and the motorcycle one on the driver's side.
AA president Edmund King said: "Those on two wheels never appear from nowhere so as drivers, we need to be more alert to other road users."
Among those involved in the launch is British Cycling policy adviser and former Olympic cycling champion Chris Boardman. There is also support from 20-times Isle of Man TT winner John McGuinness and the Metropolitan Police.
Boardman said: "This is a welcome step in creating a culture of mutual respect between all road users."
McGuinness said: "I definitely feel safer riding my bike on the track than I do on the open road."
The survey also found drivers in London were the most likely to look out for cyclists, while drivers in Wales and Northern Ireland were least likely to do so.
