The Coach, from Wheelers Travel who are based at North Baddesley near Southampton, broke down as it was turning right from Winchester Road and completely blocked the carriageway.
For nearly half-an-hour access could only be made through the forecourt of the adjacent shop. The police had to be called to direct traffic.
Eventually the vehicle was restarted and moved to Testbourne where it was parked up to await fitters.
The breakdown comes at a time when there is increasing concern over the effect of traffic in the area. Many hope that school buses will be removed from this bottleneck when the Winchester Road development is carried out where there are plans for a safe dedicated drop-off point for both buses and parents.
