Switching between User roles in AuthController.php

Hey all,

For my website I currently have three user roles ["admin", "contractor", "user"]

On my register page I have two radio button's that allow the user to select which account type they wish to create an account for. I feel the way I have coded the logic that switches validation logic etc is messy and was wondering if anyone would have any tips on how to improve it.

<?php

namespace App\Http\Controllers\Auth;

use App\User;
use Validator;
use App\Http\Controllers\Controller;
use Illuminate\Foundation\Auth\ThrottlesLogins;
use Illuminate\Foundation\Auth\AuthenticatesAndRegistersUsers;

class AuthController extends Controller
{
    /*
    |--------------------------------------------------------------------------
    | Registration & Login Controller
    |--------------------------------------------------------------------------
    |
    | This controller handles the registration of new users, as well as the
    | authentication of existing users. By default, this controller uses
    | a simple trait to add these behaviors. Why don't you explore it?
    |
    */

    use AuthenticatesAndRegistersUsers, ThrottlesLogins;

    /**
     * Where to redirect users after login / registration.
     *
     * @var string
     */
    protected $redirectTo = '/';

    /**
     * Create a new authentication controller instance.
     *
     * @return void
     */
    public function __construct()
    {
        $this->middleware('guest', ['except' => 'logout']);
    }

    /**

        ];

        $data['type'] = (isset($data['type']) && in_array($data['type'], [2,3])) ? $data['type'] : 3;

        if($data['type'] == 2) {
            return Validator::make($data, $rules['contractor']);
        } elseif($data['type'] == 3) {

            $user->assignRole('user');
        } elseif($data['type'] == 2) {
