Glasgow City Council has approved plans to introduce a 20mph speed limit across most of its roads.
The limit will apply to all residential streets, the city centre, main shopping areas and where there are high levels of walking or cycling.
The council hopes the policy, which will cost £25m to implement, will help it meet its zero carbon emissions target by 2030 and improve road safety.
Cllr Anna Richardson, city convener for sustainability and carbon reduction, said: 'First and foremost a city wide 20mph speed limit is about improving road safety. It’s well known that lower speeds reduce the risk of accidents but also reduce the severity of any injuries suffered by those involved.
'Our own initial research on the impact of 20mph zones already in place Glasgow is indicating a 31% reduction in incidents, which is hugely positive.'
