Rain is one of the most common driving hazards in Massachusetts, and one of the most underestimated. Every year, wet roads contribute to hundreds of crashes across the state, many of them involving drivers who had years of experience but were not prepared for the specific conditions they encountered. This guide covers the practical steps Massachusetts drivers need to stay safe when it rains.
Quick Answer: How Do You Drive Safely in Rain in Massachusetts?
Driving safely in rain requires slowing down, increasing your following distance, turning on your headlights, and adjusting your behavior for the specific conditions. Massachusetts law requires headlights when windshield wipers are in use.
TL;DR:
- Massachusetts law requires headlights whenever windshield wipers are in continuous use.
- Slow down by 5 to 10 mph below posted limits in rain; wet roads increase stopping distance by up to 50 percent.
- Increase following distance to at least 4 to 6 seconds in wet conditions.
- Avoid cruise control in rain; hydroplaning can occur without warning.
- The most dangerous time is the first 15 to 30 minutes of rain, when oil lifts off the road surface and mixing with water creates a slick layer.
- CMSC offers driving lessons that cover wet-weather technique for drivers of all experience levels.
What Massachusetts Law Says About Driving in Rain
Under Massachusetts General Laws Chapter 85, Section 15, drivers must use headlights whenever windshield wipers are in continuous use due to rain, snow, fog, or other precipitation. This law applies even during daytime hours. Driving without headlights in rain is a civil motor vehicle infraction.
How Much Should You Slow Down in Rain?
On dry pavement at 65 mph, a typical car needs about 300 feet to stop. On wet pavement, that stopping distance increases by 30 to 50 percent, meaning you may need 400 to 450 feet to stop from the same speed. Reduce your speed by 5 to 10 mph in light rain and more in heavy rain, standing water, or reduced visibility.
What Is Hydroplaning and How Do You Handle It?
Hydroplaning occurs when your tires ride on top of a thin layer of water instead of gripping the road surface. Signs include a sudden lightening of your steering, a feeling that the car is floating, or the rear end beginning to drift.
If you hydroplane:
- Ease off the accelerator gradually. Do not brake hard.
- Steer gently in the direction you want to go.
- Once you feel grip return, slow to a safer speed.
Hydroplaning risk is highest at highway speeds above 45 mph, on roads with poor drainage, and with worn tires. Check your tire tread before rainy season.
Safe Following Distance in Rain
In dry conditions, the minimum recommended following distance is 3 seconds. In rain, increase this to 4 to 6 seconds. In heavy rain with reduced visibility, 6 or more seconds is appropriate. Always follow at a distance that gives you time to react to sudden braking ahead.

Frequently Asked Questions
Do Massachusetts drivers have to use headlights in rain?
Yes. Massachusetts law requires headlights whenever windshield wipers are in continuous use, including daytime rain.
What is the most dangerous time to drive in rain?
The first 15 to 30 minutes of rain is often the most hazardous. Oil and debris on dry roads mix with initial rainfall to create a slick surface before rain fully washes it away.
Is it safe to use cruise control in rain?
No. Avoid cruise control in wet conditions. If your vehicle hydroplanes with cruise control on, the system may accelerate rather than reduce speed, making the situation worse.
