REPORT | Windshield Wipers Up or Down?

 Summary

The question of whether to position windshield wipers “up” (raised perpendicular to the windshield) or “down” (resting flat against the glass) during a snow storm has sparked widespread debate among drivers, automotive experts, and media outlets. This practice is particularly relevant in regions prone to heavy snowfall, where ice accumulation can impair vehicle readiness and safety. Despite extensive online discussions and expert advice, a comprehensive review of available sources reveals

no formal scientific studies, peer-reviewed research, or controlled experiments

specifically addressing this topic. Recommendations stem primarily from practical experience, automotive organization guidelines, and anecdotal evidence. This report synthesizes key arguments, expert opinions, and alternatives to help drivers make informed decisions.

Background and Context

Windshield wipers are designed to maintain clear visibility by sweeping away rain, snow, and debris. In winter conditions, snow and ice can accumulate on the windshield, potentially freezing the wiper blades in place. The “up” position involves manually lifting the wiper arms away from the glass, a hack popularized in snowy regions to mitigate ice buildup. However, this method is not universally endorsed, as it may introduce mechanical risks. The absence of empirical studies means guidance relies on expert consensus from organizations like AAA, Erie Insurance, and the National Highway Traffic Safety Administration (NHTSA).

Arguments in Favor of Raising Wipers “Up”

Proponents of the “up” position argue it offers practical benefits for winter preparedness:

• Prevents Freezing to the Windshield: Raised wipers avoid direct contact with accumulating ice, reducing the risk of blades sticking and tearing when cleared.
• Easier Snow and Ice Removal: With wipers out of the way, scraping the windshield is simpler and less likely to damage the rubber blades.
• Protects Wiper Motor: If wipers are accidentally activated while frozen, the “up” position prevents strain or burnout on the motor.

This approach is common in areas with frequent storms and is endorsed by some experts for short-term use. Arguments Against Raising Wipers “Up”Critics, including major automotive associations, highlight potential drawbacks:

• Spring Tension Degradation: Prolonged raising can stretch the internal springs, leading to reduced pressure on the glass, streaking, and poor performance over time.
• Risk of Damage from Wind or Accidental Activation: High winds during storms can slam raised arms down, potentially cracking the cold-brittle windshield or bending components.
• Mechanical Stress: Lifting too aggressively may damage gears or linkages, especially in older vehicles.

Some sources note that while spring wear is debated, it’s not significant for occasional use, but habitual raising is discouraged. Expert Opinions and Recommendations

• AAA and Affiliates: Strongly advise against routine “up” positioning due to spring stress and recommend alternatives like covers. Experts like John Paul (AAA’s Car Doctor) and Robert Sinclair Jr. emphasize long-term blade efficacy.
• Erie Insurance: Supports “up” for preventing blade and motor damage, with Harold Singh noting minimal spring wear concerns.
• Glass Doctor and Others: Favor “up” for ease but caution against over-lifting to avoid mechanism strain.
• NHTSA: Focuses on general winter prep like wiper fluid but does not specify position.

Community forums like Reddit and Quora show mixed user experiences, with many favoring “up” for convenience. Alternatives to the Up/Down DilemmaExperts recommend bypassing the debate with preventive measures:

• Windshield Covers: Insulated or magnetic covers protect the entire glass and wipers from snow/ice buildup.
• Protective Wraps: Use plastic bags, socks, or sleeves over blades to prevent freezing while keeping them down.
• Winter-Grade Equipment: Install all-weather blades with protective boots and use antifreeze washer fluid.
• Defrosting Techniques: Run the defroster and use de-icer sprays before scraping.

These options minimize risks associated with either position.ConclusionWithout scientific studies to provide definitive evidence, the choice between “up” or “down” for windshield wipers in snow storms depends on individual priorities: convenience and blade protection favor “up,” while long-term mechanical integrity leans toward “down.” Major experts like AAA recommend avoiding habitual raising and opting for covers instead. Drivers in storm-prone areas should weigh vehicle age, wind exposure, and personal habits. Ultimately, proactive winter maintenance—such as covers and quality blades—offers the most reliable solution for safe driving.Citations
