An emergency 30mph speed limit is being enforced on Richmond Hill.
Police say it's due to recent surface dressing coming loose.
Officers have put the limit in place to prevent loose chippings causing damage to other vehicles.
The constabulary says it's a legal speed reduction and enforcement action will be taken where necessary.
