What do you think are the chances of you surviving a crash where your car is hit side-on at 50 km/h?

Between 2008 and 2012, the RSA examined 867 forensic investigation files on fatal collisions. They focused on the vehicle and associated behaviour, which may have contributed to the collision.

f the 867 collisions analysed, 274 (32pc) had excessive speed for the road and conditions as a contributory factor. This may not have been the sole cause of the accident, but contributed in either full, or part, to the final outcome. Of this number, 19pc said excessive speed was the sole contributory factor.

From the observational studies we annually conduct nationwide, 80pc of drivers are breaking the speed limit in towns and cities: areas with 50kmh speed limits to protect the vulnerable.

Typically, 7-in-10 pedestrian casualties occur on roads of 50km/h or lower, highlighting the importance of drivers obeying urban limits. A majority of people also tell us through attitudinal surveys, that they believe it's okay to break the speed limits by up to 10kmh over the posted speed limit. Many don't really see this as speeding at all.

In response to these shocking findings, the RSA has produced a new anti-speeding campaign, focusing on the consequences of breaking the speed limit, by what many would consider 'going a little bit over the speed limit'. Unfortunately, for pedestrians and cyclists, there is no such thing as a little bit injured or a little bit dead.

Speed is the biggest contributing factor to road deaths. And its difference is felt acutely at low levels. When you hit someone at 50km/h, they have a 50pc chance of living. If hit at 60km/h, their chance drops to just 10pc.

Our campaign shows the danger of just this kind of speeding by low increments. The kind of speeding some drivers do without even realising. The 5kmph you go over in a daze, that doubles your chance of being involved in a casualty collision.

For the campaign, we commissioned an original song by the brilliant Irish recording artist Cathy Davey. It's a beautiful, wistful piece, which seems to detail the things our driver sees on his journey.

However, as our driver nudges his speed up, moving from 50km/h to 60km/h, it's harder and harder for the singer to keep up with the things that appear on the road: the things our driver is supposed to be noticing and reacting to. Roadside objects appear thicker and faster - it starts to become frenetic and breaks down in chaos until our final moment: Where the driver hits a young girl.

"When you're going too fast, you can't keep up with the road," we read. Our message is simple. "Slow down".

It's a hauntingly-emotive film, to remind drivers that even a small increase in speed, can have the most devastating of consequences.

The campaign was timed to go live at the same time as the gardaí mounted their recent National Slow Down Day.

This was held over a 24-hour period between 7am Friday 21st and 7am Saturday 22nd October, 2016. In total, the gardaí and GoSafe checked 135,010 vehicles. A total of 341 vehicles were travelling above the limit.

Some notable detections over the 24-hour period in 50km/h zones were:

• 75 km/h in a 50km/h zone on the R445 at Ballymany, Newbridge, Kildare.

• 69 km/h on a 50km/h zone on the R712 Pennefatherslot Kilkenny.

• 65km/h in a 50km/h zone on the N80 Newtownbarry, Bunclody, Wexford.

• 62km/h in a 50km/h zone on the R245 at Ballyraine, Letterkenny, Donegal

To put these speeds in context again. Hit at 50kmh, a pedestrian's chances of survival are the toss of a coin. Hit at speeds above that, and it reduces to less than 10pc. Drive too fast and you simply won't be able to keep up with the road.

Speed kills. The faster that you drive, the greater the likelihood that someone dies in a car accident, whether it’s you, another driver, a passenger, or a pedestrian. How fast does a car have to go to kill someone on impact? What speed does it take to die in a car crash?

In Australia, the New South Wales (NSW) Center for Road Safety conducted a study on driving speed and how it relates to traffic fatalities. It found that “driving too fast is the single biggest contributor to death and injury on NSW roads.” While alcohol use, not wearing a seat belt, and fatigue also contribute to deaths from car crashes on NSW roads, speeding is the most significant factor

The NSW Center for Road Safety also released data that shows the chances of surviving — or the likelihood of dying in a car crash at different speeds. The speed listed in the study is in kilometers per hour (kph), but for the convenience of non-metric readers, we converted it to miles per hour (mph).

The chances that a pedestrian dies in a car crash is:

  • 10% at 19 mph (30 kph)
  • 40% at 25 mph (40 kph)
  • 90% at 31 mph (50 kph)

The chances that a driver or a passenger dies in a side-impact car crash is:

  • 10% at 31 mph (50 kph)
  • 40% at 37 mph (60 kph)
  • 80% at 43 mph (70 kph)

The chances that a driver or a passenger dies in a head-on car crash is:

  • 5% at 37 mph (60 kph)
  • 10% at 43 mph (70 kph)
  • 20% at 56 mph (90 kph)

Despite increasing the risk of death in car crashes, many people drive too fast. As detailed by WKW, here are several reasons why drivers speed. This includes:

  • Drivers that run late try to get to their destination more quickly
  • Inattentiveness or not paying close attention to the posted speed limit
  • Follow the flow of traffic and drive at the same speed as other drivers
  • Aggressive driving and road rage

Why does speeding increase the likelihood of dying in a car crash?

Speeding is dangerous and increases the chances of dying in a car crash. Here are several reasons why:

  • It takes a longer distance to slow down and stop
  • Reduces the reaction time 
  • Increases the likelihood of losing control of a car
  • Increases the likelihood of a rollover accident

How to stop speeding and prevent deaths in car crashes

The dangers of speeding are clear, but many people still do it. If you’d like to break the habit of speeding and prevent you and others from dying in a car crash, then take some measures. Be sure to give yourself plenty of time to get to your destination, which will lessen your inclination to speed. 

Also, do your best to have a calm state of mind and show patience when driving. Don’t let yourself get consumed by anger when encountering the unsafe and aggressive driving behavior of others. Also, to ensure that you are attentive to the posted speed limit, ensure that you are well-rested before driving.
