Driving Efficiently & 10 Safety Tips
How driving affects the environment, fuel-saving tips, and Ontario's top 10 road safety recommendations.
How Driving Affects the Environment
Gasoline- and diesel-powered vehicles release air pollutants and gases -- among them oxides of carbon, nitrogen, and sulphur, plus hydrocarbons and soot. These pollutants:
- Harm the air we breathe, our health, and crop yields
- See hydrocarbons + oxides of nitrogen react under sunlight to create ground-level ozone (smog) -- a serious health threat behind respiratory illnesses
- Have oxides of sulphur and nitrogen bond with water vapour to make acid rain, which damages lakes, forests, and crops
- Include carbon dioxide and other heat-trapping gases that drive global warming, which can bring on droughts, crop failures, falling water levels, and storms that are both more frequent and more severe
A single car puts out less carbon dioxide than an airplane, truck, bus, or train does -- but because cars are owned by so many and driven so much, they account for nearly half of all the carbon dioxide produced by every mode of transportation combined. Passenger-heavy vehicles like buses generate less carbon dioxide per rider than cars do.
Before You Drive
- Think ahead and roll several errands into a single trip
- Stay off the road during rush hour; travelling off-peak is quicker, burns less fuel, and puts out fewer emissions
- Keep an eye on smog alerts and lean into eco-driving habits especially when smog is heavy
- For quick trips, think about walking or cycling instead
- On longer journeys, public transit is an eco-friendly substitute for driving solo
- Share the ride whenever you can; many parts of the province offer free carpool lots
While Driving
- Don't fire up the engine when you don't need to -- a cold start sends out a heavy burst of pollutants
- Shut the engine off any time you'll be parked beyond 10 seconds; a cold-weather engine still reaches operating warmth in about 30 seconds
- Stick to the speed limits -- driving fast burns more fuel and raises your odds of a serious crash
- Out on the freeway, switch on cruise control and your overdrive gear to sip less fuel
- Shed any needless weight -- heavy baggage, wet snow, leftover winter sand or salt
- Look after your car's aerodynamics -- take off roof racks and carriers when you're not using them, and at high speed use the vents rather than opening the windows
- Use the air conditioning thoughtfully -- around town and in stop-and-go traffic, rely on the windows and vents instead, though at high speed A/C usually beats open windows on fuel economy
- Don't "top off" the tank at the pump -- the fuel that spills gives off harmful vapours
At the Garage
- Servicing your vehicle regularly keeps it running at peak efficiency
- Keep the engine in good tune -- a transmission that won't shift into high gear, low transmission fluid, brakes that drag, or worn-out spark plugs can each drive fuel use up sharply
- Stick to the maintenance schedule recommended in your owner's manual
- Have a specialist look at any fluid leaks to head off engine damage and environmental harm
- Keep your tires inflated to the right pressure to trim your fuel bill, your emissions, and your tire wear
- Get your alignment checked on a regular basis to cut down on uneven tire wear and fuel use
10 Ways You Can Keep Ontario's Roads Among the Safest Anywhere
- Never drink and drive, and don't get behind the wheel while on any medication that affects your driving.
- Buckle up every time, and make sure each passenger has the right child car seat, booster seat, or seatbelt.
- Respect the speed limits, and ease off whenever the road or the weather turns poor.
- Steer clear of risks: no cutting people off, no abrupt lane changes, and no running yellow lights.
- Stay off the road whenever you feel tired, upset, or unwell.
- When in doubt, wave the other driver through -- give up the right-of-way.
- Leave at least a two-second gap to the vehicle in front. To measure it, begin counting the moment the car ahead passes a fixed landmark and stop the count when your own car arrives at that spot.
- Trim the distractions: don't pack the car too full and don't blast loud music.
- Always clear your blind spot: glance in the mirror and over your shoulder before any lane change.
- Scan traffic in every direction, sidewalks and paths or trails included, before you enter an intersection.
Tip
The two-second rule: choose a fixed landmark, start counting as the car ahead passes it, and stop when you get there. Counting under two seconds means you're too close.
Key takeaways
- Cars account for nearly half the CO2 from all transportation -- carpooling and public transit cut that down
- Shut the engine off any time you'll be parked beyond 10 seconds; a cold engine still warms up in about 30 seconds
- Strip out needless weight and take off roof racks to improve fuel economy
- Routine servicing -- proper tire pressure, tune-ups, fluid checks -- maximizes fuel economy and lowers emissions
- Skip topping off the tank -- spilled fuel gives off harmful vapours
- Lock in the 10 safety tips: seatbelts, speed limits, a two-second following gap, blind-spot checks, and yielding when in doubt
