Memory Aids
Mnemonic
Think of a RAT scurrying through hidden alleyways to avoid the main path, and a driver RUNNING their car through side streets to avoid the main road.
Conceptual Metaphor
TRAFFIC IS WATER/CONGESTION (rat-running is 'diverting the flow'), DRIVERS ARE VERMIN (sneaky, undesirable).
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not translate literally as 'крысиный бег'. It is not about rodents. The concept is 'движение по дворовым проездам/тихим улицам для объезда пробок'. A descriptive phrase is needed.
Common Mistakes
- Using it as a verb without the hyphen ('He was rat running') – the hyphenated form is standard for the noun/adjective. Applying it to any use of a side road, rather than specifically to avoid congestion on a main route.

FAQ
Frequently Asked Questions
No, the act of driving on public side streets is not illegal in itself. However, it often involves breaking speed limits or ignoring weight/access restrictions, which are illegal. Communities use legal measures like traffic orders to prevent it.
'Rat-running' implies using streets not designed for through-traffic (e.g., narrow residential roads, cul-de-sacs) purely as a shortcut to save time. Taking a signposted alternative route or using a legitimate B-road is not considered rat-running.
The metaphor compares drivers to rats, who are known for using hidden, maze-like pathways to move furtively and avoid open spaces (main roads). It suggests undesirable, sneaky behaviour.
Yes, this is a common complaint. Satnav and mapping apps often calculate the fastest route regardless of road type, directing high volumes of traffic down unsuitable local streets, thereby creating or exacerbating rat-running problems.
