Anyone with a chest under 28 inches will be banned from driving a motorbike – which make up 90% of the traffic in the country, reports the Daily Telegraph.
The idea is to prevent people who are too thin, too short or too sickly from riding a motorbike. Ailments such as enlarged livers or sinusitis will also rule out aspirant motorists.
“The new proposals are very funny, but many Vietnamese people could become the victim of this joke,” said Le Quang Minh, 31, a Hanoi stockbroker.
“Many Vietnamese women have small chests. I have many friends who won’t meet these criteria.”
The average Vietnamese man is 5ft 4ins tall and weighs less than nine stones. The average Vietnamese woman is 5ft 1in tall and weighs about seven stones.
Vietnamese bloggers have been poking fun at the plan, envisioning traffic police with tape measures eagerly pulling over female drivers to measure their chests.
“From now on, padded bras will be best-sellers,” said Bo Cu Hung, a popular Ho Chi Minh City blogger.
“I’m not heavy enough, what am I going to do?” Le Thu Huong asked in a letter to Tuoi Tre newspaper. “And what about people whose chests are small? Most of them are too poor to afford breast implants!”
