How often should I check my blood sugar while driving?

Check your blood sugar before you begin driving and approximately every 2 hours during the trip. If you feel any symptoms of hypoglycemia — such as shakiness, sweating, or confusion — pull over safely immediately and treat the low before continuing to drive.

What snacks should I bring on a road trip with diabetes?

Pack low-glycemic, portable snacks such as nuts, seeds, string cheese, peanut butter packets, jerky, and sugar-free options. Also bring fast-acting carbohydrates like glucose tablets or juice boxes specifically for treating hypoglycemia quickly.

Can I bring diabetes supplies through state checkpoints or on a ferry?

Yes. Always carry a letter from your doctor and printed prescriptions confirming your medical need for supplies and devices. Keep supplies in their original labeled packaging when possible. A medical ID bracelet is also helpful for identifying your condition quickly to any officials or emergency responders.

Where can I order extra diabetes supplies before a road trip?

MDS Diabetes at mdsdiabetes.com offers a comprehensive selection of blood glucose meters, test strips, CGM accessories, insulin delivery supplies, and travel accessories. Ordering in advance ensures you have everything you need before you leave home.

Road Trip with Diabetes: Your Complete Management Guide

Road trips are one of life's great adventures — but for people living with diabetes, hitting the open road requires more than just a full tank of gas. Unpredictable meal stops, long stretches of sitting, and disrupted routines can all impact blood sugar levels in ways that catch even experienced travelers off guard. With the right preparation and supplies, you can enjoy every mile with confidence.

Plan Your Supplies Before You Leave Home

Running out of diabetes supplies in the middle of nowhere is a stressful situation nobody wants to face. Before you pull out of the driveway, do a thorough inventory check and pack more than you think you'll need — aim for at least double your expected usage to account for spills, damage, or an extended trip.

Blood glucose meter and extra test strips — test more frequently during travel due to schedule changes
Insulin and syringes or pens — bring backup delivery devices
CGM sensors and transmitters — carry spares in case of adhesion failure
Fast-acting glucose tablets or gel — essential for treating hypoglycemia quickly
Healthy snacks — nuts, cheese sticks, and low-glycemic options to avoid gas station impulse buys
A printed prescription and doctor's letter — useful at state lines or if supplies are lost

MDS Diabetes at mdsdiabetes.com offers a wide range of testing supplies, CGM accessories, and insulin management tools so you can stock up conveniently before any trip.

Keep Insulin Safe During the Drive

Heat is insulin's worst enemy. Never leave insulin in a hot car, glove compartment, or direct sunlight. Use an insulated travel case with ice packs or a dedicated insulin cooling wallet to maintain safe temperatures between 36°F and 46°F. If you're traveling through extremely hot climates, check your insulin's appearance before each use — cloudy or discolored insulin should be discarded.

Managing Blood Sugar on the Road

Sitting for long periods naturally raises blood sugar for many people. Plan regular pit stops every 1–2 hours to stretch, walk around the rest stop, or do light movement. This simple habit can meaningfully improve your glucose levels throughout the trip.

Smart Eating Strategies at Road Trip Stops

Fast food and convenience stores can derail even the best-laid blood sugar plans. Look for grilled proteins, salads, and low-carb options when stopping to eat. Apps like Google Maps can help you locate chain restaurants with nutritional information nearby so you can pre-plan your meal and bolus more accurately.

Handling Hypoglycemia While Driving

Low blood sugar behind the wheel is a serious safety risk. Check your glucose before you start driving and again every 2 hours. If you feel symptoms of a low — shakiness, confusion, sweating — pull over immediately and treat with fast-acting carbohydrates. Do not resume driving until your blood sugar has returned to a safe level and you feel fully alert.

Use Technology to Your Advantage

A continuous glucose monitor (CGM) is a road tripper's best friend. Real-time glucose readings and alarms mean you don't have to guess — your CGM alerts you before highs or lows become a problem. Pair your CGM with a smartwatch for discreet, at-a-glance readings without reaching for your phone while driving.

Double your supply inventory and store in an accessible bag
Pack insulin in an insulated cooling case
Pre-program emergency contacts into your phone
