Generally if you are just giving required in input it will give its own validation message in html5. But if you want to give your custom message then do this.
namespace MvcAppVehicleSystem.Controllers
{
public class HomeController : Controller
{
VehicleSysHireEntities2 _db;
public HomeController()
{
_db = new VehicleSysHireEntities2();

public ActionResult Index()
{
var query = _db.VehicleRentTypes.ToList();
var query2 = _db.VehicleCategories.ToList();
var model = new Models.SelectViewModel
{
CategoryList = query2,
RentTypeList = query
};
return View(model);
}

public ActionResult Index(VehicleMasterModel role)
{
VehicleMaster currentVehicle = new VehicleMaster();
currentVehicle.Brand = role.Brand;
currentVehicle.Category = role.Category;
