In terms of prevention or mitigating harms, slight increases or decreases in the speed of your vehicle can have serious impact on the extent of your injuries.
Dr. Logan explains, “The energy [in a crash] is proportional to the square of the speed. So doubling your speed from 50km an hour to 100km an hour increases the energy that has to be dissipated by a factor of four.”
“Tripling the speed means nine times the energy.”
“If you just increase the speed of your car from 70km by 10 per cent to 77km, the energy absorbed goes up by 20 per cent. So the injuries aren’t just 10 per cent worse—they could be 20 per cent worse,” he said.
“If you decrease your speed by 10 per cent, your injuries don’t decrease by 10 per cent—they decrease by 20 per cent.
“Small changes in speed have a big effect on the outcome, both positively and negatively.”
Our bodies, as smart and well-designed as they are, can only withstand a certain force. Automotive engineering miracles aside, being cautious of your speed is still instrumental in saving lives. That’s why he always recommends that drivers stay below the speed limit. The difference could be living to drive another day.
Remember, not all injuries are apparent immediately
In crashes, it’s common to see people suffer from injuries that don’t appear right away. That’s why it’s essential to go to the nearest hospital as soon as you can. Early treatment will help prevent infections and help you be diagnosed and put on the correct treatment plan.
