Answer

If you mean a travel route, then yes, a Jain layperson can use it. In Jainism, the main principle is ahimsa (non-violence), so the better choice is the one that avoids unnecessary harm as much as possible. ( jaina.org)

Explanation

For householders, travel by road, train, or other modern transport is generally accepted when needed. Jain pilgrimage guides also note that pilgrims may travel by modern transport, while the spirit of the journey remains devotional. ( jainworld.jainworld.com)

For Jain monks and nuns, the discipline is much stricter. Traditional Jain texts and Jain sources describe ascetics as traveling on foot and not using vehicles. ( jainworld.jainworld.com)

Spiritual Understanding

In Jain Dharma, the key question is not just “Can I use this route?” but also “Can I do this with the least possible violence, attachment, and carelessness?” That is why intention, restraint, and mindfulness matter deeply. ( jaina.org)

Takeaway

So, yes for lay Jains, but always try to choose the route and mode of travel with ahimsa in mind. If you meant something else by “ara route,” please tell me the exact term.
