M1 speeds are set to be reviewed after fewer crashes occurred on the highway during the Commonwealth Games.

The speed limit was reduced by 10 km/hr on Queensland’s busiest road and Main Roads Minister Mark Bailey says a review to make these changes permanent would make it safer for drivers.

But, from the seven million trips made for the games five and a half million of them were made on public transport, bringing into question whether the potential speed reduction would increase flow capacity or the number of crashes.
