Bristol is notorious for lengthy traffic jams and motorists can find themselves stuck in congestions for hours at times.
It's not surprise then that some opt to use 'rat runs' - smaller roads, often through rural and suburban communities, which can get them to their destination quicker.
However, some of these routes are simply not designed to cope with high levels of traffic, which could put pedestrians and other road users at risk and can delays for residents.
Bristol Live asked motorists on social media to list their worst rat runs in the city and surrounding area - here's what they had to say.
1. Dunkeld Avenue, Filton
Two people named this route through Filton between Kenmore Crescent and Charborough Road as particularly bad for traffic.
2. Broomhill Road, Conham
Sue Sedley said Broomhill Road is used as short cut, leading to heavy delays for those living on the road.
She said: "We live there and have to go to work a hour or more early so we can just get off our driveway, and not get caught in a mile queue."
3. Old Quarry Road, Shirehampton
Kim Tudor said: "Drivers use this road to avoid the queue on Kings Weston Avenue.
"Definitely an 'accident waiting to happen' as several near misses already!"
4. Park Crescent, St George
Claire Downie said Park Crescent in St George is "a total nightmare and a big accident waiting to happen".
5. Hengrove Lane, Hengrove
Lisa Goodman said: "Hengrove Lane is a rat run between West Town Lane and Wells Road to Airport Road despite it being 20mph."
6. Craven Way, Longwell Green
According to Jacqui Letheby, drivers use this as a rat run rather than waiting in the dual carriageway traffic on the A4174.
7. Queensholm Crescent, Downend
Similar to the above, Suzanne Davis said this road is used to avoid the ring road A1471.
8. Queen Street, Kingswood
This road between Hillside Road and the A420 Two Mile Hill Road was named by one motorist.
9. Long Cross, Lawrence Weston
One motorist said vehicles used this road in Lawrence Weston as a cut through for Avonmouth.
10. Whiteway Road, Speedwell
Mary O'Ryan said Whiteway Road is a "nightmare" to get through these days.
11. Crown Hill. St George
Another road in St George - this time Crown Hill between Whitehall Avenue and Holmes Hill Road/Cecil Avenue.
