Abstract:<\/h2>\n

Background <\/strong><\/h3>\n

In 2010, BC introduced changes to the BC Motor Vehicle Act that targeted common driver-related risk factors for crashing.9<\/sup><\/a>

<\/div>, <\/sup>10<\/sup><\/a>
<\/div> \u00a0The new traffic laws included 1) Cell Phone Ban (Feb, 2010): Motorists who used unpermitted electronic devices while driving would be fined $167, 2) Immediate Roadside Penalties (IRPs) for drinking drivers (Sept 2010): The IRP for a first time impaired driving offence (BAC > 0.05%) is a 3-day vehicle impoundment and 3-day license suspension. Second and third offenses result in higher penalties. Drivers with a BAC > 0.08% are subject to an immediate 30 day vehicle impoundment, a 90-day license suspension, and mandatory installation of an alcohol interlock device on their vehicle for one year, and 3) IRPs for speeding (Sept 2010): The IRPs for racing or excessive speeding include 7 \u2013 60 days of vehicle impoundment.<\/p>\n

Aim<\/strong><\/h3>\n

To evaluate the effects of BC\u2019s new traffic laws on fatal crashes, insurance claims, hospital admissions and ambulance calls for road trauma.<\/p>\n

Methods<\/strong><\/h3>\n

We used de-identified administrative data and obtained approval from our institutional research ethics board. Briefly, we used autoregressive integrated moving average (ARIMA) interrupted time-series analyses to model the impact of the new laws on various types of crashes and medical events.<\/p>\n

The estimated mean reductions in alcohol, speeding and distraction related fatal crashes in British Columbia were found to be 54.8% (95%CI: 41.9, 64.9%), 32.9% (95%CI: 19.4, 44.2%) and 15.1% (95%CI: 1.4, 27.0%) indicating respective monthly decreases of 1.47, 1.16 and 0.37 fatal crashes per 1,000,000 driver population.<\/p>\n

After accounting for pre-existing trends, we found an 8.0% (95% CI: 0.6, 14.9%) reduction of in hospital admissions and a 7.2% (95% CI: 1.1, 13.0%) reduction in ambulance calls due to road trauma. These reductions correspond to a monthly decrease of 5.7 hospital admissions and 47.3 ambulance calls per 1,000,000 population.<\/p>\n

There was no reduction in the total number of insurance claims, nor for claims involving rear end collisions. There was, however, a 12.5% (95% CI: 9.2, 15.6%) reduction in claims for single night-time crashes.<\/p>\n

Our findings suggest that the amendments to BC\u2019s Motor Vehicle Act significantly reduced adverse outcomes from crashes caused by alcohol, speeding or distracted driving.<\/p>\n
