Motorists in England and Wales could face being prosecuted if they drive after downing just one pint of beer, transport minister Andrew Jones has indicated.
Scotland's drink-drive limit was lowered from 80mg of alcohol per 100ml of blood to just 50mg two years ago.
Mr Jones has revealed he is to meet his counterpart in Scotland to talk about what impact lowering the limit has had.
And ministers say Scotland's lead could be followed in England and Wales if there is strong evidence that it will help save lives and improve road safety.
Nicholas Lyes, public affairs manager for the RAC, urged the Government to lower the limit in England and Wales.
He said: "More than half of motorists think the blood-alcohol limit should be reduced at least to 50mg/100ml from the current 80mg/100ml level.
"Younger drivers are more likely to drink-drive with 26% of those between 17 and 24 thinking or knowing they have done so in the past year.
"We urge Government to listen to motorist opinion, consider carefully what is happening in Scotland and reduce the drink drive limit."
Scotland's limit is the equivalent to a pint of beer or a large glass of wine for male motorists and a small glass of wine or half a pint of beer for female drivers.
Mr Jones has said the impact of Scotland's limit needs to be gauged before the possibility of lowering it in England and Wales is considered.
Road safety experts and medical professionals have expressed concern that England and Wales now have one of Europe's highest drink-drive limits.
