Air pollution is increasing everyday in India and one of the main causative factor is vehicular transmission. Increased air pollution is related to decrease in pulmonary function. As taxi drivers work in congested roads throughout the day, they are one of the most affected populations.

This study was aimed to assess the Peak Expiratory Flow Rate (PEFR) of taxi drivers as well as the train drivers and to compare them. PEFR was assessed in 30 train drivers (Group A) and 30 taxi drivers (Group B) between the age groups of 25 to 50 years.

People in Group A (574.7 ± 2.432) performed better in this particular test compared to Group B (488 ± 6.702).

Though the present study has found out that the PEFR valueswere less than predicted values in both the groups but taxi drivers’ pulmonary function were affected more compared to the train drivers.
