Rising fuel prices have long been linked to shifts in driving behaviour, but their influence on driver aggression and harsh manoeuvres remains under investigation. This study explored the impact of fuel price changes on harsh driving behaviour in Greece from 2019 to 2022. Using statistical data and multiple linear regression models, researchers assessed correlations between fuel price trends and driving performance. Results revealed that as fuel prices increased, harsh events such as harsh acceleration or braking decreased. Interestingly, when fuel prices exceeded 1.65€/lt, harsh events dropped by 15% and the average speed declined by 8%, from 74 km/h to 68 km/h. It was revealed that higher fuel costs prompt drivers to adopt smoother, more cautious driving styles. The study also considered factors like economic pressure and environmental conditions. Policymakers might use fuel pricing and eco-driving incentives to encourage safer driving and reduce environmental impact.
