Why This Even Matters
Because without passing these tests
✅ You can’t register your car
✅ You risk fines or tickets
✅ And sometimes — you’re driving around unsafely without realising
But the rules depend entirely on where you live
Some states care
Some don’t

My Own Test Story

Failed because my number plate light was out
A £2 bulb cost me £50 in re–inspection fees and wasted time
Now I check everything myself the night before — takes 10 minutes
