Is a cracked windshield worse at night or in the rain?
Reviewed by the Skyview Auto Glass technical team — NWRD-, ASE- and DINITROL-trained technicians · Updated November 2026
Quick answer
Yes. A crack scatters oncoming headlights into glare at night, and rain or wiper blades can catch on a chip and force water into the break. The damage is more noticeable and more distracting in low light or wet weather, which is why a crack in the driver’s view is taken seriously.
How a crack behaves at night and in the rain
- A bright scatter or starburst when oncoming headlights hit the crack
- The fracture refracts the light, which is far more visible in the dark than in daylight.
- A wiper blade that catches or chatters over the damage
- The blade edge is hitting the chip or crack, which can force water in and spread the break.
- Water pooling inside the crack after rain
- Moisture in the break weakens a future repair and can let dirt settle in.
Why a cracked windshield causes glare
A crack in laminated glass creates a fracture line that bends light differently from the surrounding glass. In daylight you may barely notice it, but at night the oncoming headlights hit that fracture and scatter into a glare or starburst right in your field of view. The effect is strongest when the crack is in the driver’s direct line of sight.
Rain makes it worse in a different way. Wiper blades run across the glass, and a blade that catches on a chip can chatter, smear, and push water into the break. Water inside a crack weakens a later resin repair and can carry dirt that leaves a visible line.
What makes a crack worse to drive with
- A crack in the driver’s direct line of sight, where glare is most distracting.
- A chip the wiper blade catches on, which can spread the damage.
- Rain or washer fluid getting into the break, which weakens a repair.
- Night driving, when the scatter from headlights is most visible.
More questions about cracks at night and in the rain
Does a cracked windshield cause glare?
It can. The fracture bends light differently from the surrounding glass, so oncoming headlights scatter into a glare or starburst at the crack. The effect is most noticeable at night and when the crack is in your line of sight.
Is it safe to drive with a crack in the rain?
A small chip away from your view is usually fine in the rain, but a crack the wipers catch on can spread, and water in the break weakens a later repair. Cover a fresh chip with clear tape and book a repair soon.
Do wipers make a crack worse?
They can. A blade that catches on a chip can chatter and push water into the break, which weakens a repair and can spread the damage. Have a chip in the wiper path repaired before it grows.
