Distraction is a factor in approximately 25% of all collisions. Using a handheld mobile phone while driving is illegal in Sweden and significantly increases crash risk — comparable to driving at the legal alcohol limit.
The Law
Using a handheld device for any purpose while driving is prohibited — this includes calls, texts, navigation, music selection, and photography. Hands-free calling is permitted but still increases cognitive load. The law applies when the vehicle is moving; it does not apply when stationary with the engine off.
The Risk
A driver reading a text for 5 seconds at 90 km/h travels 125 metres without looking at the road — the length of a football pitch. Reaction time while on a phone (even hands-free) is 50% slower than normal. Lane keeping deteriorates sharply.
Other Distractions
Eating, adjusting the radio, arguing with passengers, and looking at roadside events (rubber-necking) all impair driving. The key principle is that your primary task is driving — all other activities must wait or be done when safely stopped.
Exam tip: Mounting a phone as a satnav is legal only if it is set up before driving and you do not touch it while moving. Reaching to tap the screen at traffic lights is still an offence if the vehicle is not parked with the engine off.
