Winter Driving Guide

Overview

Driving in the Finnish winter is completely different from summer driving. Snow, ice, darkness, and sub-zero temperatures transform familiar roads into death traps. This guide teaches you to navigate the frozen wasteland of Peräjärvi safely.

Whether you drive a FWD Sorbett or RWD Corris Rivett, winter driving demands complete adaptation of your driving style, route planning, and vehicle preparation.

Winter Driving Fundamentals

The Physics of Winter Driving

Reduced Traction:

• Summer tire on snow: 20% of dry road traction
• Winter tire on snow: 60-70% of dry road traction
• Winter tire on ice: 10-20% of dry road traction
• Summer tire on ice: 5-10% of dry road traction

Key Principle: Traction is everything. Everything else (speed, braking, turning) depends on it.

Vehicle Dynamics Changed:

| Condition | FWD (Sorbett) | RWD (Rivett) | 4WD | |-----------|---------------|--------------|-----| | Acceleration | Good | Poor | Excellent | | Braking | Equal | Equal | Equal | | Turning | Understeer | Oversteer | Balanced | | Overall Safety | Good | Dangerous | Best |

Essential Mindset Changes

Summer vs. Winter Driving:

Summer Mindset:

• Speed = Efficiency
• Aggressive driving OK
• Reaction time ~1 second
• 100% traction available

Winter Mindset:

• Smooth = Safe
• Gentle inputs only
• 3x reaction time needed
• Traction is precious

Golden Rules:

1. Everything slower - Acceleration, braking, turning
2. Everything gentler - Smooth pedal/steering inputs
3. Everything earlier - Brake, turn, accelerate sooner
4. Everything further - Following distance, margin for error

Vehicle Preparation

Critical Winter Equipment

Tires (MANDATORY):

| Type | Price | Traction | Lifespan | Recommendation | |------|-------|----------|----------|----------------| | Summer | N/A | 20% | N/A | NEVER use in winter | | All-Season | 600-800 mk | 40% | 40,000 km | Minimum acceptable | | Winter | 800-1,200 mk | 70% | 30,000 km | STRONGLY RECOMMENDED | | Studded | 1,000-1,500 mk | 80% | 25,000 km | Best for ice |

Why Winter Tires Matter:

• Rubber compound - Stays soft in cold
• Tread pattern - Sipes bite into snow
• Edge effects - Better grip on curves
• Shorter stopping - 30-50% less distance

Installation:

• All four wheels - Never mix tire types
• Before first snow - Don't wait
• Proper inflation - Cold reduces pressure
• Alignment check - Uneven wear dangerous

Other Essential Equipment

Block Heater (~400 mk):

• Plugs into outlet - Pre-warms engine
• Essential below -15°C - Reliable starting
• Install at PSK - Professional installation
• Use nightly - In extreme cold

Battery Blanket (~150 mk):

• Wraps battery - Keeps warm
• Plugs in - Heats battery
• Extends life - Cold kills batteries
• Essential for old batteries

Winter Wipers (~40 mk):

• Special rubber - Won't freeze
• Heavier frame - Pushes snow
• Visibility critical - Can't drive blind
• Replace yearly - UV and cold damage

Emergency Kit:

• Blankets - Warmth if stranded
• Food/water - Survival supplies
• Shovel - Dig out of snow
• Sand/salt - Traction aids
• Flashlight - Visibility
• Jumper cables - Battery failure

Winter Driving Techniques

Starting & Acceleration

Cold Engine Start:

1. Turn key - Don't press gas
2. Let warm up - 2-3 minutes minimum
3. Gentle throttle - 1500-2000 RPM max
4. Wait for temp - Until heater blows warm
5. Test brakes - Before moving

Acceleration:

1. Gentle input - Smooth throttle application
2. Higher RPM - Within reason (2000-3000)
3. Avoid wheel spin - Traction loss
4. Build speed slowly - No rush
5. Straight line - Avoid accelerating in turns

⚠️ WARNING:

• Never floor it - Spins wheels, goes nowhere
• Avoid high RPM - Traction limited
• FWD advantage - Power to driven wheels
• RWD disadvantage - Rear breaks loose

Braking Techniques

The Physics:

• Ice = frictionless - Brakes don't work well
• ABS helps - Don't pump (modern cars)
• Distance 3x longer - Than dry roads
• Gentle pressure - Hard braking = skid

Braking Process:

1. Start early - Begin braking sooner
2. Gentle pressure - Smooth application
3. ABS pulsing - Normal, don't lift
4. Look where going - Not at obstacle
5. Steer around - If possible

Emergency Braking:

1. Full brake pressure - Don't ease up
2. Don't steer hard - Maintain direction
3. ABS will pulse - This is normal
4. Be prepared - May not stop in time
5. Prepare for impact - If unavoidable

Skid Recovery:

1. Don't panic - Stay calm
2. Steer into skid - Rear sliding left, turn left
3. Gentle inputs - No sudden moves
4. Light off gas - Let traction return
5. Regroup - Then continue carefully

Cornering

Principles:

1. Slow down BEFORE turn - Not during
2. Gentle steering - Smooth inputs
3. Accelerate gently OUT - Exit speed controlled
4. Avoid mid-turn braking - Very dangerous
5. Wide turns - Give yourself margin

Understeer (FWD pushing wide):

• Too fast - Reduce speed
• Ease off gas - Let tires grip
• Don't turn harder - Makes it worse
• Gentle correction - Smooth steering

Oversteer (RWD rear stepping out):

• Steer into slide - Rear going right, turn right
• Gentle throttle - Too much = more slide
• Don't panic - Countersteer smoothly
• Experience helps - Practice in safe area

Following Distance

Rule of Thumb:

• Summer: 3 second rule
• Winter: 8-10 second rule
• Ice: 12+ second rule
• Heavy snow: 15+ second rule

Counting Method:

1. Pick fixed point - Sign, tree, mark
2. When car ahead passes - Start counting
3. Count "one-thousand-one..." - This = 1 second
4. When YOU reach point - Check count
5. Need 8+ in winter - Adjust speed

Factors Requiring More Distance:

• Ice patches - Invisible hazards
• Heavy snow - Poor visibility
• Night driving - Limited sight
• Old tires - Reduced traction
• Heavy vehicle - Longer stopping

• Steep hills - Hard to climb/stop
• Narrow roads - No margin for error
• River/lake roads - Ice risk

Navigation in Winter

GPS Reliability:

• Good for routes - Shows way
• May not know conditions - Not weather-aware
• Battery drain cold - Carry charger
• Signal issues - Valleys, forests

Backup Navigation:

• Paper map - Old school backup
• Landmarks - Know key locations
• Mile markers - Track progress
• Local knowledge - Ask at Teimo's

Time Planning

Speed Reductions:

• Clear roads: -20-30% speed
• Light snow: -40-50% speed
• Heavy snow: -60-70% speed
• Ice: -70-80% speed

Trip Time Calculation:

1. Check weather - Current + forecast
2. Add 50% time - For safety
3. Plan fuel stops - Don't run low
4. Tell someone - Your route/timing
5. Have backup plan - Alternate routes

Example:

• Summer trip: 30 minutes
• Winter weather: Add 50% = 45 minutes
• Add safety buffer = 1 hour total

Specific Vehicle Types

FWD Vehicles (Sorbett)

Advantages in Winter:

• Engine over drive wheels - Better traction
• Predictable handling - Understeer bias
• Better hill climbing - Power to front
• Easier to control - Less tail-happy

Driving Style:

• Normal techniques work - Just smoother
• Power on early - Use engine weight
• Steer gently - Front tires grip limited
• Brake early - Distance increases

Limitations:

• Not invincible - Still limited traction
• Can get stuck - In deep snow
• Front-heavy - Nose dives in bumps
• Avoid aggressive driving - Still dangerous

RWD Vehicles (Corris Rivett)

⚠️ DANGEROUS IN WINTER ⚠️

Disadvantages:

• Power to rear wheels - Oversteer risk
• Rear can step out - Unexpected
• Hard to control - Requires skill
• More accidents - Statistics prove it

Survival Techniques:

1. Winter tires MANDATORY - No exceptions
2. Reduce speed - 40-50% of summer
3. Gentle inputs - All the time
4. Avoid hard acceleration - Rear breaks loose
5. Steer into oversteer - Countersteer smoothly

When RWD is Deadly:

• Ice - Rear loses grip instantly
• Snow acceleration - Wheelspin = no go
• Cornering fast - Tail slides out
• Wet roads - Hydroplaning risk

Recommendations:

• Use FWD for daily - Sorbett or similar
• RWD only when necessary - Project car
• Avoid winter driving - Store it
• Practice in safe area - Learn handling

4WD/AWD Vehicles

Best Winter Choice:

• Power to all wheels - Maximum traction
• Predictable handling - Balanced
• Confident driving - Feels secure
• Best safety - If driven properly

Still Not Invincible:

• Can still crash - Going too fast
• Braking same - All wheels brake
• Can get stuck - Deep snow
• Expensive - Higher fuel, maintenance

Best Practices:

• Use appropriate tires - 4WD ≠ winter tires
• Reduce speed - Still limited traction
• Plan routes - Use 4WD capability
• Avoid unnecessary risks - Still dangerous

Emergency Situations

Skidding

What Happens:

• Loss of traction - Tires slide
• Loss of control - Car goes where momentum takes it
• Natural instinct wrong - Panic braking/steering

Recovery Steps:

1. Stay calm - Panic kills
2. Remove foot from gas - Let engine braking slow
3. Steer into skid - Rear sliding left, turn left
4. Gentle inputs - No sudden moves
5. Regain control - Then continue slowly

Prevention:

• Slow down - Most effective
• Gentle inputs - Smooth driving
• Winter tires - More grip
• Avoid sudden moves - Everything gradual

Getting Stuck

Signs You're Stuck:

• RPMs high - But not moving
• Snow flying - Wheels spinning
• No forward motion - Despite acceleration

Unsticking Techniques:

Rocking:

1. Shift to forward - Gentle gas
2. When stops moving - Shift to reverse
3. Gentle gas - Reverse
4. Repeat - Rock back and forth
5. Gradually build momentum - Eventually free

If Rocking Fails:

1. Stop spinning - Damages tires, gets stuck deeper
2. Dig out wheels - Clear snow
3. Use traction aids - Sand, salt, cat litter
4. Gentle rocking - With cleared path
5. Call for help - If still stuck

Traction Aids:

• Sand - Best option
• Salt - Melts ice, then grip
• Cat litter - Works in pinch
• Floor mats - Last resort
• Branches - Branches, pine boughs

Breakdown

What to Do:

1. Pull over safely - Off road if possible
2. Hazard lights on - Be visible
3. Call for help - Phone, flares
4. Stay with vehicle - Shelter
