Here's why:
* Safety: Riding on the left side allows you to see oncoming traffic, especially in areas with limited visibility. It also makes it easier to judge distances and avoid collisions.
* Courtesy: It's a common courtesy to ride on the left side of the road to avoid obstructing other road users.
* Legal in many places: In many countries, riding on the left side of the road is a legal requirement.
However, there are some exceptions:
* Australia and New Zealand: These countries drive on the left side of the road, so riders also ride on the left.
* Specific areas: In some areas, local rules or customs may dictate a different side of the road for horse riding.
Always check the local rules and regulations before riding your horse on the road. It's also a good idea to wear bright clothing and use a reflective vest for increased visibility, especially when riding in low light conditions.
