Lights on Campaign
At the launch of the several Road Safety Campaigns, the Department of Transport has urged motorists to drive with their headlamps on during the day. Motorists were urged to keep the headlamps of vehicles on the dipped beam and demonstrate their commitment and support of the Arrive Alive’s ‘Lights on the campaign’.
It is important to understand the merits behind this request. Several international studies have proven that the correct implementation of such a strategy could indeed assist in reducing deaths on the roads.
Even though circumstances and environmental conditions might differ the following international studies have provided noteworthy findings in countries where daytime running lights are used in vehicles:
- In Denmark in 1990 two studies evaluated the daytime running lights law, one that assessed short-term effects, the other looking at longer-term effects. Results of these two studies were quite consistent. There was a small reduction in daytime multiple-vehicle crashes (7%) in the first year and 3 months the law was in effect, with one type of daytime running lights relevant crash (left turn in front of the oncoming vehicle) reduced by 37%. In the second study, which covered 2 years and 9 months of the law, there was a 6% reduction in daytime multiple-vehicle crashes, and a 34% reduction in left-turn crashes. There was a small reduction in motor vehicle-cyclist collisions (4%) but a statistically significant increase (16%) in motor vehicle-pedestrian collisions.
- In a study in Canada comparing 1990 model year vehicles (required to have daytime running lights) with 1989 vehicles, a statistically significant 11% reduction in daytime multiple-vehicle crashes other than rear-end impacts was estimated. This estimate was adjusted to take into account the fact that about 29% of 1989 vehicles were fitted with daytime running lights.
In 1994 Avis, Inc. announced the results of a traveller-safety study analysing the incidence and degree of damage to cars equipped with daytime running lights; the study showed a significantly greater degree of damage to those without daytime running lights. Those equipped with daytime running lights have their headlights on at all times and are more visible to other drivers. During the day, they are on at an 80% power level; in the dark, they operate at 100%.
