Because often there are icy roads,
Icy roads coated with darkest ice,
They can make vehicles slip & crash,
All slip not only out of the icy roads,
But even into each other they collide,
These call for going slow in Oslo,
'Cause reasons suchlike prevail.

Neither snow chains can help much,
Nor being an expert driver help you,
No other thing is going to help you..

Help yourselves & others too,
Just go slow in Oslo...
