A new study from the University of Newcastle (UoN) has found a targeted online intervention can significantly reduce mobile phone use among young drivers.

Led by social psychologist Dr Cassandra Gauld, the research focused on drivers aged 18-to-25.

The study tested a combined educational and behavioural approach to curb smartphone use behind the wheel.

“Studies show that up to 85% of young drivers may use their phones while driving – whether to call, text, take photos or use apps,” Dr Gauld said.

“Despite having a general awareness of the dangers associated with that usage as well as the legal penalties, those aged 18-to-25 years continue to use their phone.

“This project allowed us to develop new, theory-driven approaches to reduce this risky behaviour.”

The study surveyed 175 young drivers across Australia, measuring behaviour before the intervention, then again after one week and four weeks.

Participants were split into four groups, with the strongest results seen among those who completed both the educational and behavioural components.

“In that group, 73% reported reducing their phone use one week later, and 67% were still reporting reduced use after one month,” Dr Gauld said.

“That’s a meaningful and sustained reduction, particularly given how normalised phone use has become for many young drivers.”

The intervention included a purpose-built website featuring evidence-based information, practical strategies and short-form videos designed to challenge common myths about phone use while driving.

“We know that simply telling young people ‘don’t use your phone’ is unlikely to change behaviour,” Dr Gauld said.

“These videos directly challenge common beliefs such as ‘I can multitask’ or ‘I only check it at red lights’.

“Addressing those misconceptions is critical.”

The study also used a psychological technique known as an “induced hypocrisy intervention”.

This encouraged participants to reflect on their own unsafe behaviour after endorsing safe driving practices.

“The approach taps into internal motivation rather than relying solely on rules or enforcement,” Dr Gauld said.

With young drivers overrepresented in crash statistics nationwide, the findings could help shape future road safety programs aimed at reducing distraction and preventing avoidable harm.

“These findings demonstrate that carefully designed, evidence-based digital interventions can make a measurable difference,” Dr Gauld said.
