City council transport manager Martin Parkes said the size of the roundabout and the large volumes of traffic meant there was always potential for accidents involving larger vehicles.
"The ultimate plan is to get rid of the roundabout and put in traffic signals."
The other most common accidents where Tauranga Bay Hopper drivers were at fault involved clipping or hitting seven parked cars. Driver fault was also responsible for rear-ending three stationary cars.
None of the accidents involved injury to passengers and no action was taken against drivers by police.
The proposal to install signals on Chadwick Rd roundabout has been opposed by businessmen who look out across the intersection.
Leigh Crockford of Crockford Real Estate said there was the odd mishap but accidents were rare. "Roundabouts keep spitting traffic out but lights hold you up for quite a while."
The only hassle for traffic through Greerton's shopping centre was the Cameron Rd pedestrian crossing.
Greerton Barber's Jim Keown said lights would be a disaster and jam things up. Even rush-hour traffic flowed reasonably well through the roundabout. "You don't see many accidents."
Darryl Bellamy, the operations director for Go Bus, the company which operates the Bay Hopper service, said their drivers were constantly looking in their mirrors to give themselves space when they were on the roundabout.
"It is tight but not impossible. There is enough room if people play the game."
