Another Coffee? Why Too Much Caffeine Could Cost You More Than a Latte
We’ve all been there - the long commute home after a tough day, eyelids drooping, and that little voice saying, “Just one more coffee will get me through it.”
It feels harmless - a quick caffeine hit to keep you alert. But what if that extra shot actually makes you a risk on the road?
Caffeine and Driving: Friend or Foe for Road Safety?
Grabbing a strong coffee before a long drive feels like the perfect fix for tiredness. After all, caffeine boosts alertness and focus - it’s the world’s go-to pick-me-up.
But too much caffeine can trick your brain into feeling awake when you’re still tired, slowing your reactions and clouding judgment - a dangerous mix for anyone behind the wheel.
Research shows that drivers who rely on multiple coffees or energy drinks to fight driver fatigue are more likely to be involved in accidents. That’s because caffeine doesn’t replace sleep - it only masks tiredness.
Hidden Dangers of Too Much Caffeine While Driving
Realistically, most of us don’t measure our caffeine intake. A large coffee here, an energy drink there… it all adds up.
Too much caffeine can cause:
- Jitters and shaky hands, which can make steering more dangerous.
- Anxiety and restlessness, which distract you from the road.
- Overconfidence, which might make you drive faster or take unnecessary risks.
- Dehydration, which contributes to fatigue and slower reactions.
So even though caffeine can feel like a lifesaver, overdoing it can make you a hazard - to yourself and others.
The Real Fix for Driver Fatigue
No amount of coffee can replace proper rest. If you’re feeling drowsy on a drive:
- Pull over and take a short break - even 15–20 minutes can help.
- If possible, share driving duties or plan rest stops.
- Stretch and give your eyes a rest from the road.
The Highway Code recommends taking a break every two hours on long journeys to rest and recuperate. While caffeine in moderation can be surprisingly effective, treat it as a tool- not a solution.
When Too Much Coffee Costs You More Than a Spill
When over-caffeination turns into a lapse in concentration, it’s not just your alertness that suffers - your bank balance might too.
Here’s where it gets serious: accidents caused by tired or over-stimulated drivers aren’t uncommon - and they can be financially devastating.
Even a minor bump can lead to repair bills running into thousands, and if your car is written off, your insurer’s payout might not cover what you still owe on finance.
That’s where GAP Insurance comes in.
If your car is written off after an accident, MotorEasy GAP Insurance bridges the gap between your insurer’s payout and the amount you paid (or still owe) for your vehicle. It’s peace of mind that your coffee habit won’t leave you out of pocket if the worst happens.
Think of it as your financial caffeine - a boost of protection when you need it most.

The Bottom Line
When it comes to caffeine and driving, balance is key. A cup of coffee can perk you up, but it’s not a cure for fatigue.
Before your next journey, ask yourself:
- Am I rested enough to drive safely?
- Am I relying on caffeine instead of sleep?
- Do I have the right cover in place if something unexpected happens?
- Your body - and your wallet - will thank you for thinking ahead.
So next time you’re about to grab that third coffee before the motorway, remember: what your body really needs might not be caffeine – it’s a break.
And for everything else, MotorEasy’s GAP Insurance has your back- protecting you from the financial fallout of any accident, coffee-fuelled or otherwise.
