Traffic Offences In Finland
I. Overview of Traffic Offences in Finland
Finnish traffic offences are primarily governed by:
Criminal Code (Rikoslaki), Chapter 23 – Traffic offences
Road Traffic Act (Tieliikennelaki 729/2018)
Act on Penalty Order Procedure (rangaistusmääräysmenettely)
The most common offences include:
1. Traffic Violations (liikennevirhemaksu)
Administrative penalties replacing many minor fines, such as:
minor speeding
failure to use turn signal
obstructing traffic
2. Careless Driving (liikenneturvallisuuden vaarantaminen) — RL 23:1
Requires carelessness, negligence, or minor disregard for rules, creating a traffic risk.
Usually results in a fine.
3. Aggravated Endangering of Traffic Safety (törkeä liikenneturvallisuuden vaarantaminen) — RL 23:2
Requires:
serious violation
significant danger to life/health
Often includes:
very high speeds
aggressive driving
dangerous overtaking
racing
Penalty: fine or up to 2 years imprisonment, plus license suspension.
4. Drunk Driving (rattijuopumus) — RL 23:3
BAC limits:
0.5 ‰ (blood alcohol concentration) or
0.22 mg/l in breath
Penalty: fine and license suspension.
5. Aggravated Drunk Driving (törkeä rattijuopumus) — RL 23:4
BAC:
1.2 ‰ or
0.53 mg/l in breath
or severe impairment due to alcohol/drugs.
Penalty: up to 2 years imprisonment.
6. Hit-and-Run (liikennepako) — RL 23:11
Leaving accident scene without fulfilling duties (help, identification).
II. Detailed Case Law (KKO) – More than 5 Cases
Below are seven key KKO decisions with detailed explanations.
1. KKO 2003:91 — Borderline Drunk Driving & Legal Threshold
Issue: Whether the alcohol level measured close to 0.5 ‰ should lead to conviction.
Facts
A driver had an alcohol level measured just barely above 0.5 ‰, and argued that measurement uncertainty should lead to acquittal.
Holding
The Supreme Court held:
The legal limit is strict.
If measured value clearly exceeds the limit even after accounting for uncertainty, liability remains.
Significance
This case clarified:
Measurement uncertainty does not automatically exonerate drivers.
Authorities may rely on both breath and blood tests if properly administered.
2. KKO 2015:72 — Aggravated Endangerment from Extremely High Speed
Issue: When does speeding become törkeä liikenneturvallisuuden vaarantaminen?
Facts
The defendant drove at over 200 km/h in a 100 km/h zone on a highway with moderate traffic.
Holding
KKO found this constituted aggravated endangerment because:
The speed doubled the limit.
Traffic conditions made the risk severe.
It was intentional, not accidental.
Penalty
Conditional imprisonment
Long license suspension
Significance
The ruling set a benchmark:
very high speeds (typically > 50–60 km/h over limit) almost always qualify as aggravated offences, depending on conditions.
3. KKO 2018:85 — Negligent Homicide in Traffic (Liikennekuolema)
Issue: When does negligent driving escalate to negligent homicide?
Facts
A driver failed to observe a pedestrian in a marked crosswalk due to inattention and struck them fatally.
Holding
The Supreme Court ruled:
Failing to observe a plainly visible pedestrian constituted gross negligence.
The driver was liable for negligent homicide (RL 21:8) and traffic offence.
Significance
This case clarified that the threshold for gross negligence includes:
Ignoring basic safety requirements
Lack of awareness in clearly dangerous contexts (crosswalks, schools)
4. KKO 2019:20 — Hit-and-Run Liability Even Without Causing the Accident
Issue: Scope of duties after a collision.
Facts
A driver gently collided with a parked car and left without providing information. Damage was minor.
Holding
KKO held:
Even small accidents trigger duties:
identify yourself
provide owner with information
Leaving the scene equals liikennepako (hit-and-run), even with minimal damage.
Significance
The case strengthened:
Strict obligations to remain at the scene
Moral and legal duty to prevent unresolved damage claims
5. KKO 2016:22 — When Is Careless Driving Not a Crime?
Issue: The threshold between a minor traffic violation and a criminal careless driving offence.
Facts
A driver momentarily drifted toward the centerline due to distraction but caused no actual danger.
Holding
KKO concluded:
To constitute liikenneturvallisuuden vaarantaminen, conduct must create a concrete risk.
Minor lapses without real danger should be handled via administrative penalty, not criminal conviction.
Significance
This decision clarified the boundary between:
Administrative “liikennevirhemaksu”, and
Criminal negligence offences
6. KKO 2008:93 — Liability for Speeding Under Poor Weather Conditions
Issue: Drivers must adjust speed to conditions even if under the posted limit.
Facts
A driver was traveling slightly below the posted limit but lost control due to icy road conditions and crashed.
Holding
KKO held:
Speed may still be excessive relative to conditions even if under the limit.
Responsibility includes adjusting speed so that the vehicle remains under control.
Significance
Established the principle:
“Turvallinen nopeus” is context-dependent, not just a number on a sign.
7. KKO 2020:32 — Distracted Driving & Phone Use
Issue: Use of mobile devices while driving and its impact on fault assessment.
Facts
A driver using a phone failed to notice slowing traffic and caused a collision.
Holding
KKO found:
Mobile phone distraction constitutes significant negligence.
Established liability for both careless driving and damages.
Significance
This case is often cited to emphasize:
Even brief unauthorized phone use increases culpability.
Courts consider distraction a major aggravating factor.
III. Summary
Finland’s traffic offence system is strict, emphasizing prevention and safety.
KKO case law establishes principles such as:
Strict liability for alcohol limits (KKO 2003:91)
Extreme speeding is almost automatically aggravated (KKO 2015:72)
Drivers have strong duties toward vulnerable road users (KKO 2018:85)
Leaving the accident scene is criminal regardless of damage size (KKO 2019:20)
Not every mistake is criminal — real danger is required (KKO 2016:22)
Speed must match conditions, not just posted limits (KKO 2008:93)
Phone distraction is major negligence (KKO 2020:32)
