Objectives: Many medical conditions and medicines with therapeutic importance have been shown to impair driving skills, causing road traffic accidents, which leads to great human and economic suffering in Oman.

The primary purpose of this study was to assess retrospectively the extent of medical conditions and medications influencing road traffic safety among drivers involved in road accidents.

Methods: We conducted a retrospective study among 951 injured or non-injured drivers who reported to Khoula and Nizwa hospitals.

Results: The majority of victims were male (72.0%), involving personal cars, and reported at Khoula Hospital.

The results show that 7.6% of the victimized drivers had a history of medical conditions with diabetes and hypertension (36.1% each) the most common.

About 4.0% of victims were on medications of which insulin was the most common (9.4%).

Loss of control was contributed to 38.5% of cases followed by dizziness (25.6%), sleep amnesia (10.3%), and blurred vision (7.7%).

Other effects blamed by victimized drivers include vertigo, phonophobia, photophobia, back pain, loss of sensation, and headache accounting for 17.9% of cases.
