“Must You Check Under Your Car for Sleeping Kids in Denmark? Nope.”
A widely-shared claim states Danish law requires drivers to check under their vehicle for sleeping children before starting the engine. No such law exists in Danish legislation.
Origin and Spread of the Claim
This claim has circulated online since at least 2012, when the popular Twitter/X account UberFacts tweeted it to millions of followers. From there, it was copy-pasted — without any citation — across dozens of 'weird laws' travel blogs, car rental company websites, and viral listicles, accumulating a veneer of credibility through sheer repetition.
Search Finds No Such Law
An exhaustive search of the Danish Road Traffic Act (Færdselsloven), official EU driving guides for Denmark, the Danish Road Directorate (Vejdirektoratet) publications, and comprehensive Danish traffic law overviews finds absolutely no provision mandating a pre-departure under-vehicle check for children or anyone else. Danes themselves, when asked, consistently say they have never heard of this requirement.
A Related Myth Debunked Too
The myth appears to have a close sibling: a slightly different version claims Danish law requires drivers to check their lights, brakes, and steering — and even honk the horn — before each trip. Even this version was flagged by the University of Copenhagen's own student publication, which published an editorial correction noting it appeared to be an urban myth they could not verify.
Possible Origin of the Myth
Denmark, like most countries, imposes a general duty of care on drivers to operate their vehicles safely. Denmark also has a well-known cultural practice of leaving babies to nap unattended outdoors in prams.
Where the story gets it wrong
Many travel and motoring sites present this as an established, enforceable Danish law, with versions claiming it covers 'children' or 'anyone.' None cite a statute or section number. It is often listed alongside real Danish traffic laws, lending it false legitimacy — but the 'sleeping children' detail does not appear anywhere in the Færdselsloven.
CLAIMED (not real): Before starting a vehicle, Danish drivers are legally required to inspect underneath their car for sleeping or hiding children. No statute in the Danish Road Traffic Act (Færdselsloven) contains this requirement.
